Single-carrier FDMA (SC-FDMA) is a frequency-division multiple access scheme. Like other multiple access schemes (TDMA, FDMA, CDMA, OFDMA), it deals with the assignment of multiple users to a shared communication resource. SC-FDMA can be interpreted

first, this project simulates cdma network using 63 gold code over Rayleigh fading channel.then ,compares rake receiver performance with ordinary receiver and theory awgn and theory Rayleigh channel . finally , we observe decreasing ber when number o

matlab实现cdma多用户检测几种算法比较 此模型是的信号发生器是由b.mat的simulink模型动态生成，共有10个用户，扩频信号是由gold码或产生，共有恒模算法、子空间算法、改进型恒模算法和最小能量检测算法等几个算法程序。-matlab achieve cdma multi-user detection Several algorithms compare this model is the signal generator is dynamically generated by

these peak-reducing signals are built by using spreading codes that are either dynamically selected those users that are known to be idle, or deliberately reserved a priorifor PAPR reduction purposes. The concept of adding orthogonal signals for peak
