摘　　要：从消除多址干扰和满足FCC频谱掩膜要求的角度出发,提出了一种使用正交Hermite脉冲的超宽带系统多址通信方法。该方法利用频-时域脉冲生成和时域正交脉冲相结合的思想,设计了正交Hermite脉冲,在此基础上,将直序扩频多址与波分多址相结合,系统中每个用户使用正交Hermite脉冲。仿真结果表明,该方法的调制信号能够较好地满足FCC频谱掩膜的要求。当系统同步良好时,与使用单一脉冲的DS-BPSK多址调制相比,该方法能有效降低系统BER,提高了系统的抗干扰能力。To overcome the multi-user interference and meet the FCC spectrum mask, a multi-access communication mehtod based on orthogonal Hermite pulses was proposed. Each user of the system was assigned an ortbogonal Hermite pulse. The simulation results indicate that the proposed modulated signals can effectively meet the FCC spectrum mask, and the proposed system has a lower BER than the conventional DS-BPSK system with the same pulse.
