Multiuser OFDM with Adaptive Subcarrier, Bit, and Power Allocation BY- J.Yashashchandra.Rao (jyashashchandra@yahoo.com)

DS-CDMA链路中加入基于子空间的PASTd多用户检测方法。系统中采用m序列阔频，可以通过高斯信道或瑞利信道。可以直接运行得到不同信噪比下的误码率曲线。(DS-CDMA link added Subspace-based multiuser detector PASTd. M sequence used in the system wide-band, Gaussian channel, or by Rayleigh channel. Get different signal to noise ratio can be run directly under the BER curves.)

实现BPSK的载波同步，采用的方法是锁频环，最大似然法频率估计(BPSK carrier synchronization is realized,the method is frequency - locked loop and maximum likelihood frequency estimation)
