Definitions
- the invention relates to a receiving unit with at least two signal receivers for analog received signals according to the digital or analog standard, analog-digital converter for converting the analog received signals into digital received signals, and with a signal processing unit for the digital received signals.
- the invention further relates to a method for receiving analog received signals, in particular broadcast signals, with such a receiving unit.
- radio receivers for the reception of amplitude-modulated (AM) and frequency-modulated (FM) reception signals often have more than one signal receiver, for example in order to receive an audio signal on a first channel and at the same time data on a second channel.
- the data can be encoded according to the Radio Data Standard (RDS), for example, or transmitted in the Traffic Message Channel (TMC).
- RDS Radio Data Standard
- TMC Traffic Message Channel
- the multiple signal receivers can also be used to transmit multiple broadcast standards, such as frequency modulation (FM), digital audio broadcast (DRB), digital radio Musice (DRM), in band on channel (IBoC) or satellite digital audio radio service (SDARS). to receive with a receiving device.
- FM frequency modulation
- DDRB digital audio broadcast
- DRM digital radio Mondiale
- IBoC in band on channel
- SDARS satellite digital audio radio service
- the multiple signal receivers can also be used to determine which ones can be received
- the analog received signals are picked up by the antenna with signal receivers and amplified in a pre-stage after band-pass filtering. With a mixer controlled by an oscillator, the bandpass-filtered and amplified analog received signal is mixed to an intermediate frequency, intermediate-frequency filtered and amplified again.
- the analog received signal processed in this way in the signal receiver is converted with an analog-digital converter for each signal receiver into a digital received signal and further processed digitally in a subsequent signal processing unit.
- the performance requirements for the analog-digital converter are relatively high.
- the analog-to-digital converters should have a high scanning speed, great dynamics and the lowest possible power consumption and should be integrated into an integrated circuit together with other functions if possible.
- the object of the invention is therefore to provide an improved receiving unit with which the chip area, costs and power requirements for the analog-digital converters can be reduced.
- the object is achieved with the generic receiving unit according to the invention in that at least one adder is clamped to the output of the signal receiver for adding the analog received signals.
- the output of the adder is connected to the input of a common analog-to-digital converter.
- the subsequent signal processing unit is designed to separate the added received signals.
- the signal amplifiers have mixers for mixing the analog received signals at different intermediate frequencies.
- At least one signal receiver should be designed to mix an analog received signal on an intermediate frequency and at least one other signal receiver for receiving and filtering a defined receive frequency band and adding this receive frequency band to the intermediate frequency signal.
- the intermediate frequency signal in the digital signal receiver can be easily separated from the rest of the reception frequency band.
- the plurality of signal receivers are provided for the simultaneous reception of analog received signals on different channels and / or according to different transmission standards. Different reception channels and different standards can thus be received and further processed in the digital part of the reception unit.
- Another object of the invention is to provide an improved method for receiving analog received signals which requires less effort for the receiving unit.
- the task is solved with the generic method by the steps:
- FIG. 1 - block diagram of a conventional receiving unit with several signal receivers and one analog
- FIG. 2 Block diagram of a receiving unit according to the invention with several Signalempfä ⁇ gern and a common analog-to-digital converter.
- FIG. 1 shows a block diagram of a conventional receiving unit for the simultaneous reception of a plurality of analog received signals on the same or different reception channels and / or according to the same transmission standards.
- Each signal receiver 2 has a preamplifier 3 with a bandpass filter 4 and a preamplifier 5.
- the input of the preamplifier 3 is connected to an antenna 6 and the output of the preamplifier 3 is connected to a mixer 7.
- the mixer 7 is controlled by an oscillator 8 in order to ab ⁇ umische ⁇ the analog received signal to an intermediate frequency IF.
- the intermediate frequency signal ZF is filtered in an intermediate frequency filter 9 and then amplified with an amplifier 10.
- Each signal receiver 2a has an analog-digital converter ADC in order to convert the amplified analog intermediate frequency signal into a digital received signal and then digitally process it further with a signal processing unit (not shown).
- FIG. 2 shows a block diagram of a receiving unit according to the invention with three signal receivers 2a, 2b and 2c.
- the two signal receivers 2a and 2b have a preamplifier 3, a mixer 7 with oscillator 8, an intermediate frequency filter 9 and an amplifier 10 in a known manner.
- the third signal receiver 2c only has a preamplifier 3 with bandpass filter 4 and preamplifier 5, see above that the band
- pass filter 4 defined reception frequency band is passed on the reception frequency and not on the intermediate frequency IF.
- the analog received signals are then added to the respective frequency with adders 11 to form a common analog received signal, with different intermediate frequencies IF. and IF 2 should be used in order to be able to easily split the common received signal later using digital channel filtering.
- the addition / reception signal is converted into a digital reception signal with a common analog-digital converter ADC and processed in a subsequent digital signal processing unit 12.
- the individual received signals are split again in the digital signal processing unit 12 by channel filtering.
