Problems solved by technology
[0003] When the transceiver system in the prior art is receiving signals, the path loss and shadow attenuation between the transmitter and receiver will cause the strength of the signal in the channel to change during transmission, resulting in the weakening of the received signal , at the same time, because the transmission needs to change the frequency, the signal will fluctuate and be unstable during the transmission, and the signal disorder will be reproduced in severe cases. When the path loss in the channel is too large, the frequency and amplitude phase error inside the channel will become larger. resulting in channel mismatch
