Digital Receiver Design and Implementation for Chirp UWB

文章针对超宽带通信技术快速发展的需要,设计了一个Chirp超宽带数字接收机。该接收机使用数字匹配滤波器避免了模拟滤波器带来的巨大插入损耗,并可以使用较为简单的方法实现时间同步。在硬件实现上,利用单比特量化匹配滤波器系数降低接收机的资源占用。实验表明该接收机结构简单、资源占用少、性能较好。

To satisfy the high speed development need of uhra-wideband communication technology, a digital receiver for chirp Ultra-Wideband （UWB） is proposed. The receiver employs digital matched filter to avoid large insertion loss of analog filter and to utilize a simple timing synchronization method. In the hardware implementation, one-bit quantification of the matched filter＇s coefficients is chose to reduce the receiver＇s resources consumption. Simulations and experiments show that the receiver has simple structure, low resources consumption and good performance.
