适用于LR-WPAN的新型TR-UWB接收机

A UWB Transmitted Reference Receiver for Low-Data-Rate Wireless Personal Area Network

针对发送-参考（TR）接收机噪声影响较敏感的缺点，提出一种适用于低速率无线个域网的新型超宽带（UWB）TR接收机设计方案．该方案一方面利用脉冲信号的自相关函数具有较强的抗多径抑制噪声影响，另一方面充分利用密集多径信道环境下信号传输的特征改善接收性能，同时在实现上较简单．与传统的TR-UWB系统相比，在相同的多径信道环境下该方案性能提高约5～6dB．

Aiming at the coherent disadvantage of transmitted reference （TR） receiver, a new TRUWB （ultra-wideband） receiver design scheme for low-data-rate wireless personal area network （WPAN） is proposed. The scheme not only takes into account noise suppression, but also considers the characteristics of signal transmission in dense multi-path environment. Computer simulation verifies the novel TR-UWB receiver can significantly improve the receiver performance.
