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

重点研究了全数字QAM接收机中的两个关键技术——符号同步和信道盲均衡。研究Gardner定时误差检测算法，盲均衡方面，重点研究了CMA及其改进算法，采用MMA算法和DD-LMS算法联合均衡 (Focuses on the all-digital QAM receiver in the two key technologies- the symbol synchronization and channel blind equalization. Research Gardner timing error detection algorithm, blind equalization, the focus of the CMA and its improved algorithm, using the MMA algorithm and the DD-LMS algorithm for joint equalization)

这是正交空时分组码中使用16QAM调制的源程序(16qam for OSTBC )

说明：  基于MATLAB语言实现了BPSK、QPSK和QAM在数字通信中的误码率性能，并与理论性能进行了比较。实现了两个发射天线的分集，分析了分集提高误码率性能的原因和实质。(Based on MATLAB language, the BER performance of BPSK, QPSK and QAM in digital communication is realized and compared with the theoretical performance. The diversity of two transmit antennas is realized, and the reason and essence of diversity improving BER performance are analyzed.)

LFM线性调频波的MATLAB仿真 利用matlab软件设计匹配滤波器。具体包括： 1）：阐述脉冲压缩（匹配滤波）的基本原理； 2）：输入信号为线性调频信号，存在的噪声信号为白噪声； 3）：通过脉冲压缩处理，讨论输出信噪比的改善。 (The the LFM chirp wave MATLAB simulation using matlab software design matched filter. Specifically including: 1): elaborated pulse compression (the basic principle of the matched filter) 2): the input signal is a chirp signal, the noise present in the signal is white noise 3): by a pulse compression processing discussed output SNR improved.)

通过MATLAB做一个用户登录的GUI页面，实现登录、注册等功能(Make a user login GUI page through MATLAB to realize login, registration and other functions.)
