使用tapi实现的用语音modem进行接电话并播放wav文件的程序(A program which is realised by tapi, and in which a call is picked up and wav files can be played through voice modem )

巴特沃斯滤波器C语言实现,低通滤波器,IIR(Butterworth filter C language implementation, low pass filter, IIR)

MIMO系统的ZF和MMSE预编码算法-4发4收(ZF and MMSE MIMO system pre-coding algorithm-4 of 4 admission)

这个matlab代码仿真了M-QAM的传输。M的取值不同，调制方式分别为4QAM，16QAM，64QAM等。传输信道为AWGN信道，能出误码率曲线。(The matlab code simulation of the M-QAM transmission. The value of M, the modulation mode of 4QAM, 16QAM, 64QAM. The transmission channel is AWGN, the BER curves.)

matlab中离散信号小数点时延的实现算法,可以精确实现一段序列的延时(numerical time-delay)

说明：  In order to solve the problem of low bandwidth utilization while the peak-to-average power ratio(PAPR) is reduced.

16QAM光信号信号调制，传输以及解调解调(16QAM signal modulation and demodulation)

信道估计方面的参考，初学者会有很大帮助，基于OFDM系统，有最基本的算法仿真和对比(Channel estimation in terms of reference for beginners will be of great help to the OFDM-based systems, simulation and comparison of the basic algorithm)

A differential QPSK modem using the TMS320C6711 DSK

自己需要给出坐标，GPS测距。主要是实现了基于maltab测距GPS测距原理(you should give coordinates, GPS ranging)
