研究了频率选择性瑞利衰落信道中的同步MC-CDMA系统上行链路空时信道估计及多用户检测算法。
The space-time channel estimation and multiuser detection algorithm for the uplink of multicarrier CDMA (MC-CDMA) system in frequency selective Rayleigh fading channel were investigated.
针对瑞利衰落信道中突发模式的空时网格编码的多电平连续相位调制(STTC - MCPM)系统，提出了一种基于数据辅助的符号定时估计算法。
A data aided symbol timing estimation algorithm was proposed for burst-mode space-time trellis coded multi-level continuous phase modulation (STTC-MCPM) systems in Rayleigh fading channels.
目前，一种普遍的解决方法是将空时码与正交频分复用（OFDM）相结合，但需要假定信道变化缓慢，从而有足够的时间通过发送训练序列来进行信道估计。
Now, a general solution is that combining STC with OFDM, but it is supposed that the channel changes slowly, so there is enough time to transmit the training sequence for channel estimation.
