摘　　要：高速数据传输IFDMA(interleaved frequency-division multiple-access)系统中,信道扩展将导致严重的符号间干扰,为此,根据IFDMA-SIMO(single-input multiple-output)系统特性,提出了一种新的基于IFDMA-SIMO系统的信道压缩算法。仿真和比较表明,该算法在保持多用户信号正交的基础上,能有效地抑制多径干扰。In high-speed IFDMA systems, the increase of channel memory can lead to serious multi-path interference. After a brief introduction to IFDMA system, a new channel shortening algorithm based on the presented IFDMA-SIMO system model was proposed. Simulation results show that the proposed algorithm can effectively suppress multi-path interference while maintaining the orthogonality among the signals from different users.
