signal detection in mimo ofdm system using qrdmdfe algorithm

对OFDM系统进行自适应分配，主要对子载波，比特和功率进行分配，已达到降低发射端功率的目标。(Adaptive Allocation for OFDM systems, the main pair carrier, bit, and power distribution, has reached the goal of reducing the transmitter power.)

说明：  lower的原版关于sift算法的资料，很难找的哦。本文非常详细的介绍了sift算法，并与常用的边缘检测算法作了比较，是学习sift算法的好资料。(lower of the original information on the sift algorithm, it is difficult to find, oh. This very detailed introduction to the sift algorithm, and with commonly used edge detection algorithms are compared, is the learning algorithms sift the good information.)

说明：  用MATLAB实现对一语音信号用不同小波进行分解，提取各层的高低频系数，画出各系数波形，并重构。(MATLAB voice signal to a different wavelet decomposition, from the high levels of low-frequency coefficients. he painted the waveform coefficients, and Reconstruction.)
