Based on the above, Fig. 2 illustrates a kind of channel transmission signal alignment provided in an embodiment of the present invention
The schematic flow sheet of method.A kind of channel transmission signal alignment method provided in an embodiment of the present invention is applied to includes M biography
The communication system of defeated passage, M is the integer more than 1.A kind of channel transmission signal alignment method provided in an embodiment of the present invention
Can be realized by channel transmission signal alignment device.As shown in Fig. 2 the method includes：
Step 201, obtains the flag bit of the transmission signal of each transmission channel in M transmission channel；
Step 202, according to the flag bit of the transmission signal of any two transmission channels in M transmission channel, it is determined that taking the post as two
Delay duration between the transmission signal of individual transmission channel；
Step 203, according to the delay duration between the transmission signal of any two transmission channels, to any two transmission channels
Transmission signal is alignd.
In the embodiment of the present invention, the flag bit of the transmission signal of each transmission channel in M transmission channel is obtained, therefore can
According to the flag bit of the transmission signal of any two transmission channels in M transmission channel, the transmission of any two transmission channels is determined
Delay duration between signal, and then according to the delay duration between the transmission signal of any two transmission channels, to any two biographies
The transmission signal of defeated passage is alignd, so that the alignment procedure of the transmission signal without manually participating in multiple transmission channels, section
Manpower is saved；Further, the scheme alignd to the transmission signal of multiple transmission channels with respect to artificial mode, this
The scheme used time in inventive embodiments is less, improves the efficiency of transmission signal alignment.
