The optimization of communication channel is the key to ensure the communication quality and reduce the bit error rate of wireless communication. A new optimization technology of wireless communication channel based on baud interval equalization is proposed to realize the equalization design of wireless communication channel. Combined with the tapped delay line model, a wireless communication channel model is constructed to suppress the channel phase offset in the channel multipath component. The decision feedback modulation method is used to design the baud-interval equalizer to realize amplitude equalization, phase and delay equalization of the wireless communication channel , To achieve channel optimization and improvement. The simulation results show that the proposed algorithm can optimize the channel, the phase offset of the channel is effectively suppressed, the channel equalization performance is better and the bit error rate of wireless communication is reduced.
