Since the AD9361 maximum transmit power is only 8dBm, the radiation range is limited, and a power amplifier is added to this in fig. 5, so that the final transmit power reaches 28dBm. The downlink receiving link is basically the reverse process of the uplink transmitting link, and because the AD9361 is integrated with high-performance low-noise amplifier, the chip can be directly connected with the receiving antenna, and special low-noise amplifier is not needed; the channel equalizer 1 is used for compensating distortion of a wireless channel, the synchronization module 1 is used for realizing carrier synchronization, bit synchronization and frame synchronization of a received signal and is used for coherent demodulation of QPSK, the synchronization module 1 also controls the pseudo-random sequence generator 2 to generate a pseudo-random sequence which is completely consistent with the content of the pseudo-random sequence generator 1 at a transmitting end but has fixed delay in time, and the pseudo-random sequence and LDPC decoded data are subjected to modulo-2 sum operation again, so that data decryption operation can be completed, and finally obtained communication information is sent to a remote instruction decoding module of the field data processing subsystem.
