(embodiment 2)
Followingly receiver module in the present embodiment 2 is described and uses the receiving element of this receiver module with reference to Fig. 2.Do not do the identical of special instruction herein, with embodiment 1.
Embodiment 2 is that with the difference of embodiment 1 as shown in Figure 2, switch portion 39 is arranged between first loop filter 23 and second loop filter 31.
Diversity control part 17 makes switch portion 39 adjust signal as amplification degree from the detected signal level of first test section of first loop filter 23 and offers second loop filter 31 when switching receiver module 3 from single accepting state to the diversity reception state.
Under the square one, there be not the transfer characteristic situation yet different with the transfer characteristic of second converter section 32 of first converter section 24 in the characteristic of the characteristic of first acceptance division 6 and second acceptance division 7.Therefore, by with will offer the 2nd AGC handling part 35 by the AGC magnitude of voltage after the conversion of first converter section 24 and compare, will by before the conversion of first converter section 24, the detected signal level of first test section directly offers the 2nd AGC handling part 35, the AGC voltage that offers second enlarging section 16 more approaches final stable certain value.Its result is, since 7 operations of second acceptance division, the time that finally converges to till the certain value to the AGC voltage that offers second enlarging section 16 can shorten more.
And, if under the situation about only being provided at short notice by first test section, 22 detected signal levels of an AGC handling part 34 to the 2nd AGC handling parts 35, the AGC voltage that offers second enlarging section 16 might be subjected to the influence from the unstable signal of second test section 30.For preventing such situation, preferred switch portion 39 will offer the 2nd AGC handling part 35 by first test section, 22 detected signal levels in the scheduled time that second acceptance division 7 is operated.Thereby the AGC voltage that can reduce to offer second enlarging section 16 is subjected to the possibility from the influence of the unstable signal of second test section 30.Its result is that since 7 operations of second acceptance division, the time that finally converges to certain value to the AGC voltage that offers second enlarging section 16 can more positively be shortened.
Further, switch portion 39 is the scheduled time before second acceptance division 7 switches to operation from not operation only, first test section, 22 detected signal levels is offered the 2nd AGC handling part 35 also be fine.Thereby, when 7 operations of second acceptance division, because first test section, 22 detected signal levels have offered the 2nd AGC handling part 35, so the time loss that produces can reduce switch portion 39 and will offer the 2nd AGC handling part 35 time by first test section, 22 detected signal levels.Its result is, since 7 operations of second acceptance division, finally converge to certain value to the AGC voltage that offers second enlarging section 16 till the time can shorten.
In addition, be arranged at receiver module 3 under the situation of less receiving element such as mobile phone, first antenna 1 and second antenna, 2 positions close to each other are provided with, and therefore the variation of first test section, 22 detected signal levels is similar substantially to the variation of second test section, 30 detected signal levels.Therefore, switch portion 39 is preferably at the fixed time according to the variation of first test section, 22 detected signal levels, and the signal level of this variation is offered the 2nd AGC handling part 35.Thereby since 7 operations of second acceptance division, the time that finally converges to certain value to the AGC voltage that offers second enlarging section 16 can shorten more.
And switch portion 39 can add first test section, 22 detected signal levels that the signal level of predetermined deviant offers the 2nd AGC handling part 35 as amplification degree adjustment signal.If will directly offer the 2nd AGC handling part 35 by first test section, 22 detected signal levels, the amplification degree of pairing second enlarging section 16 of signal level that may be received by second antenna 2 becomes not enough.Its result, in this case, the amplitude level that offers the 2nd AD converter section diminishes, the receiving feature deterioration.But, add that by level the signal level of deviant offers second enlarging section 16 with first test section, 22 detected signals, can reduce the possibility of the deterioration in characteristics of the signal of exporting from second enlarging section 16.
And, the optimum value of this deviant according to multipath reception with the reception environment that move to receive etc. and different, therefore by can reasonably controlling from the suitable value of external setting-up.For example, electronic controller (electronic volume control) (not shown) is set in second enlarging section 16, and will can be installed in the receiving element of the present invention in order to the terminal of controlling this electronic controller.As required, this terminal can be connected with computer, can set optimal side-play amount.
Demodulation section 8 can comprise further that the level coefficient correlation calculates portion (not shown), and it is used to calculate the coefficient correlation between first test section, 22 detected signal levels and second test section, the 30 detected signal levels.The relation that coefficient correlation changes for two level of expression value, one variation is totally independent of under the situation of another variation, coefficient correlation is 0, and is relevant more each other, then the absolute value of coefficient correlation is more near 1.Therefore, the absolute value of the coefficient correlation of being calculated by this level coefficient correlation portion of calculating is under the situation more than the predetermined threshold value, and it is relevant to judge that two level change, and near the optimum value of AGC voltage.In this case, switch portion 39 will offer the 2nd AGC handling part 35 by first test section, 22 detected level.Therefore, since the operation of second acceptance division 7, the time that finally converges to till the certain value to the AGC voltage that offers second enlarging section 16 can shorten really.
And, under the different situation of the directive property of two antennas, because according to reception environment coefficient correlation difference, therefore, by can realizing suitable control from the threshold value of external setting-up coefficient correlation.For example, can be in receiving element of the present invention the built-in electronic controller (not shown) of giving the threshold value of this coefficient correlation.And the terminal that will control this electronic controller is arranged at receiving element of the present invention.If necessary, this terminal can be connected with computer, can set the threshold value of optimal coefficient correlation.
In addition, as shown in Figure 3, switch portion 40 also can be arranged at the outside that demodulation LSI is a demodulation section 8.For example, the switch portion 40 of analogue type is arranged on the outlet side of a DA converter section 25, and is connected in the input side of second enlarging section 16.
