DOA估计

QPSK using system generator

说明：  在单径瑞利信道中，设计一种时分的导引辅助的信道估计方法，用Simulink和m语言进行仿真，测量BPSK的误码率性能，画出比特信噪比与误码率的关系曲线，并与理论误码率曲线进行对比(In the single path Rayleigh channel, a time-division guidance aided channel estimation method is designed. The simulation is carried out with Simulink and M language. The BER performance of BPSK is measured, and the relationship curve between bit signal-to-noise ratio and BER is drawn, and compared with the theoretical BER curve)

基于RWG奇函数的矩量法的阻抗矩阵部分的编程代码(Programming code of impedance matrix part of moment method based on RWG odd function)

说明：  频谱感知，生成采样频率，进行能量检测，采用matlab算法(Spectrum sensing, generation of sampling frequency, energy detection, using matlab algorithm)

说明：  均匀线阵估计相干信源DOA,运用空间平滑，Toeplitz矩阵法、矢量重构等方法实现(Uniform linear array estimation of coherent source DOA)

可以产出LDPC_802.16e码字，不同码长不同码率(creat LDPC_802.16e ldpc code)

光通信OFDM系统下的ACO-OFDM和DCO-OFDM系统实现和比较( U5149 u901A u4FE1OFDM u7CFB u7EDF u4E0B u7684ACO-OFDM u548CDCO-OFDM u7CFB u7EDF u5B9E u73B0 u548C u6BD4 u8F83)

cdma系统matlab仿真，在两个用户的背景下采用了直接扩频码实现扩频解扩，bpsk调制解调，程序已经运行过，没有问题！(Establishment of multipath channel model)

J2ME开发精解原码 第5章内容 大家多多交流 共同提高(J2ME development of sperm solution Chapter 5 of the original code the content of many U.S. exchanges enhance common)

利用matlab实现ASK和FSK调制解调过程对比他们的不同(Using MATLAB to realize the modulation and demodulation process of ASK and FSK, their differences are compared.)
