Simulation research of wireless communication system of LDPC code based on the adaptive modulation and precoding joint optimization technology

In order to improve the wireless communication system reliability and throughput, the adaptive modulation and preceding joint optimization wireless communication system model is designed Simulated experiments of this joint optimization wireless communication system model are done in VC++ environment. The experimental results show that the designed wireless communication system of LDPC code based on the adaptive modulation and precoding joint optimization technology can considerably increase wireless transmission system throughput, and has Lowerber BER than Higher-order modulation preceding wireless communication system.
