摘要
针对短波高速数据通信中存在的突发深衰落和严重的符号间干扰问题,通过在频域构造滤波器,提出一种单载波频域空间分集均衡联合处理算法。由于充分利用了时域和空域信息,系统接收端性能大大提高。仿真结果表明,算法具有计算复杂度低、抗误码性能好的优点,能够很好地适用于远程短波高速率数据通信系统。
To solve the problem of deep fading and severe inter symbol interference in HF high data rate transmission systems, a novel single carrier frequency domain iterative combining-equalization algorithm is proposed based on the designing of joint optimization filter. For the full utilization of space and time domain information, the performance of the system is greatly improved. Simulation results show that the proposed algorithm has significant complexity advantages and BER performance over traditional time domain algorithms. Hence it has wide implementation in remote HF communication.
