说明：  实时声音采集，双通道采集声音信号，并且进行降噪处理和FFT变换(Real time sound acquisition)

说明：  雷达点迹关联与点航关联的matlab程序(Matlab program of radar dot correlation and dot correlation)

说明：  极化码极化信道仿真，信道极化是信道合并与信道分裂两种信道操作的结果。在上述两种操作下，原本相同的N个W信道产生了极化现象，其中一部分信道的信道容量趋近于1，另一部分信道的信道容量趋近于0。(Channel polarization is the result of channel merging and channel splitting. Under the above two operations, the original n w channels have polarization phenomenon. The channel capacity of one part of the channel approaches to 1, and the channel capacity of the other part approaches to 0.)

仿真了不同距离下的多径信道衰落模型，包含大尺度衰落和小尺度衰落。(The multipath channel fading model at different distances is simulated, including large scale fading and small scale fading.)

说明：  大规模MIMO中采用天线选择来降低系统复杂度和成本，其中包括最优天线选择和递减天线选择，快速天线选择和基于范数的天线选择算法。(Antenna selection is used in large-scale MIMO to reduce system complexity and cost, including optimal antenna selection and decreasing antenna selection, fast antenna selection and antenna selection algorithm based on norm.)

说明：  跨平台即时通信技术在无线网络的研究与实现。(Cross-platform instant messaging technology in the wireless network and its implementation.)

msk调制及在AWGN信道中的误码率仿真(MSK modulation and bit error rate simulation in AWGN channel)

iEEE 601 标准 信道编码相关 卫星通信(the standard channel iEEE 601 encoding related satellite communications)

说明：  实现turbo码编程，是matlab源程序。(matlab program of turbocoder)
