卷积码编码及其维特比译码matlab实现(Convolutional coding and Viterbi decoding matlab implementation)

说明：  基于rls自适应滤波的matlab程序，实现对声音信号的去噪，效果明显(Rls adaptive filtering matlab based program, to achieve the sound signal denoising, obvious effect)

实现多用户MU，通过两次预编码来消除用户间干扰和流间干扰，同时这种处理极大简化了接收机复杂度。(MU-MIMO 。 the first precoding ：ZF-BD the second precoding ：ZF or MMSE)

This code is useful for multi user mimo systems

采用AR法模拟风速，计算时间较短，但精度相对于谐波叠加法略差(AR method using simulated wind speed, the calculation time is shorter, but the accuracy is slightly worse relative to the harmonic superposition)

说明：  基于MR的频率优化，详细描述MR频率优化的计算方法(Optimization based on the frequency of MR, MR detailed description of the method of calculating the frequency optimization)

说明：  本程序是暂态稳定分析程序，3机9节点模型，对其在pt时刻7号节点发生三相短路故障，并在ct时刻将故障切除进行仿真，最后绘出2号和1号发电机的功角差与时间的关系曲线。发电机模型采用三阶模型，忽略阻尼，电枢电阻取为零；励磁系统仅有量测和放大环节，忽略反馈和电压调节器；负荷采用恒定阻抗负荷。(This program is a transient stability analysis program, three machine nine node model, which has three-phase short circuit fault on node 7 at Pt time, and cut off the fault at CT time for simulation, and finally draw the relationship curve between power angle difference and time of generator 2 and 1. The generator model adopts the third-order model, neglecting the damping and taking the armature resistance as zero; the excitation system only has the measurement and amplification links, neglecting the feedback and voltage regulator; the load adopts the constant impedance load.)

蒙特卡洛QPSK编码，画出星座图（含噪声）并将模拟误码率与理论值比较(Monte Carlo QPSK encoding, constellation diagram drawn (including noise) and simulated bit error rate compared with the theoretical value)
