NOMA系统级仿真，多用户，多径瑞利信道(NOMA System Level Simulation)

LDPC coded OFDM system for power line communication in the presence of both AWGN and Impulsive noise..

说明：  cpofdm信道模型仿真，通过仿真得到cpofdm信道模型的复杂度和在各种信噪比下的误码率(Through the simulation of cpofdm channel model, the complexity of cpofdm channel model and the bit error rate under various SNR are obtained)

BPSK调制在高斯信道下的性能，误比特率和信噪比的曲线(BPSK modulation performance under gaussian channel, signal to noise ratio and bit error rate curve )

802.3af/at标准,POE 供电协议(standard of 802.3af/at)

实现BPSK的载波同步，采用的方法是锁频环，最大似然法频率估计(BPSK carrier synchronization is realized,the method is frequency - locked loop and maximum likelihood frequency estimation)

在多周期CPU的基础上设计一个前导0检测程序。(A preamble 0 detection program is designed on the basis of multi period CPU.)

在做毕业设计时编写的程序，主要内容是高铁环境下LTE系统的切换算法研究，源码中含scm信道模型。(a simulation about handover in LTE under high-speed railway station environment, which involving scm channel model.)

说明：  截获接收机采用时频分析进行跳频通信的参数估计程序(Intercepting the parameter estimation procedure of the receiver for time-frequency analysis for frequency hopping communication)
