摘要:
研究了频率选择性信道下基于训练序列的两发射天线的空时分组编码-单载波频域均衡系统的信道估计算法.提出了2种新SCFDE和Alamouti空时分组码相结合的传输帧结构,一种是选取m序列作为训练序列,另一种是选取具有恒幅特性的Chu序列作为训练序列.文中通过详细的理论推导得出这2种传输帧结构的信道估计算法.仿真结果表明:相对于m序列,当误码率为10-3时,以Chu序列作为训练序列的帧结构设计方案可以获得0.8dB的信噪比增益.
Abstract:
Channel estimation scheme was presented in training sequences based on single-carrier frequency domain equalization system with space-time block coded transmission with two transmit antennas over frequency- selective fading channels. Two new transmission frame structures combining SCFDE with STBC are proposed in the systems. One is m-sequences selected as the training sequences. The other is Chu sequences which have constant envelope both in time and frequency domains selected as the training sequences. The conclusions provide theoretical support for the channel estimation algorithms of two new transmission frame structures. Simulation results show that relative to m-sequences, when the bit error rate is 10-3, the frame structure employing Chu sequences as the training sequences can gain 0.8dB signal to noise. It is better than that employing m-sequences approach.
