superheterodyne

这个程序是matlab的灰度变换程序我也是往上下的(Gray-scale transformation)

CDMA业务信道卷积解码实现，根据上下行信道区分生成不同码率的卷积码序列，original_sequence是原始输入序列，channel_select是信道选择参数，其中下行码率为1/2，上行信道为1/3 (CDMA business channel decoder Convolutional achieve, according to the distinction between upper and lower line to generate a different channel bit rate of the convolutional code sequence, original_sequence is the original input sequence, channel_select is channel selection parameters, which downlink bit rate of 1/2, upstream channel for the 1/3)

这是一个有关海面船只的检测程序，考虑多普勒频移，效果很好(This is a sea vessel detection program, considering the Doppler shift, a good effect)

论述了BPSK、QPSK、16QAM、2FSK 调制和解调基本原理，以及各种调制方式的在AWGN 信道和平坦Raleigh 信道下的误码性能。同时介绍了OFDM 的调制解调原理。并使用MATLAB编写程序，对其进行了实验仿真。(It discusses the BPSK, QPSK, 16QAM, 2FSK basic principles of modulation and demodulation, and various modulation error performance in AWGN channel and flat Raleigh channel. Also introduces the principle of OFDM modulation and demodulation. Using MATLAB programming, simulation experiment was carried out.)
