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

The invention discloses a balanced time delay module and a transceiving frequency conversion channel system with the balanced time delay module, and belongs to the field of transceiving frequency conversion channel systems. The invention discloses a transceiving frequency conversion channel system with a balanced delay module. The transceiving frequency conversion channel system comprises a transmitter, a receiver, the balanced delay module, a detection module and an amplification module, according to the invention, the channel model is established through channel measurement, so that the maximum information amount and the transmission quality which can be transmitted in a transmissible channel can be obtained; according to the invention, the equalizer is added to each channel, and the path loss and shadow attenuation between the emitter and the receiver are detected by emitting multiple beams of detection signals, so that the transmission pass is equalized, and when the frequency response of the channel and the frequency response of an ideal channel are within a fluctuating error range after the equalizer is added to each channel, the equalization of the channels is completed; andmeanwhile, a control network is established in the channel transmission network, so that mutual balance and stabilization between the established channel and the load and between the established channel and the system are realized after the channel is balanced.
