histogram equalization step by step demonstration

多目标优化问题，用matlab来实现，即实现了图像功能，更能够体现人的思想(Multi-objective optimization problem, using matlab to achieve, namely to achieve the image function, better able to reflect people' s thoughts)

BER verses SNR in ofdm with amplifier: The BER performances of OFDM systems over the AWGN channel are given by the BER where N=512. We see that SNR required for BER=10-3 No channel coding scheme is adopted. Therefore, BER is a bit higher. The results with 16 QAM show that the required Signal to Noise Ratio (SNR) for BER=10-2 is almost the same. This is because the noise is the dominant.

ZF-SIC、MMSE-SIC检测算法实现，及误码率对比，带检测信道的所有行最小二范数的函数(ZF-SIC, MMSE-SIC detection algorithm, and the error rate compared with all the lines to detect the smallest two-channel function norm)

关于端点检测的几种方法，语音样本是自己录制的，对传统算法做了一些改进，加入了去噪，去噪之后再进行端点检测，均调通 vad0303：自己设置调整门限为一定值 vad0310：根据能量值和过零率设置门限，自适应门限值 vad0310_2：基于比例因子的门限自调整 vad0310.m加入了噪声，端点检测前都噪声进行了处理 entropy.m：基于自适应子带频谱熵的稳健性语音端点检测 可用于语音增强及端点检测 dbdoor.m：双门限算法，用于语音端点检测。可以通过调整门限值，并加入门限自适应算法，实现语音端点检测(Several methods on endpoint detection, recording their own voice samples, the traditional algorithm has made some improvements, adding a de-noising, and then after de-noising endpoint detection are transferred through)

matlab程序，读取txt文件中的波形数据，并画图显示。(matlab program, read the txt file in the waveform data, and drawing show.)

these are the gold codes used in the cdma systems.
