摘　　要：提出一种基于正交Hermite脉冲的超宽带通信系统方案。该方案将波形域分集概念引入到多天线超宽带系统中,拓展了常规空时编码的概念,有效提高了短距离、高速率无线通信的性能;采用合适的脉冲波型,在不同天线之间构成波形正交,代替常规的编码正交,简化了发射机和接收机的复杂度。仿真结果表明,该方案性能良好,不仅适用于块衰落信道,同样适用于快衰落信道。A novel UWB communication system is proposed based on orthogonal Hermite pulse. Pulse shape diversity is introduced into MIMO- UWB system, which develops the conventional space- time coding scheme and efficiently boost the performance of short- range wireless communication system with high speed. Adopting pulse shape, the orthogonality is realized by the orthogonal pulse instead of the coding scheme, which decreases the complexity of transmitter and receiver. The good performance is proved by the simulation under fast fading channel and block fading channel.
