摘要
根据PPM调制方式的特点和实际接收到的超宽带脉冲信号波形的特征,采用基于能量检测的接收机方案,用门控能量检测电路,将射频检测与同步捕获相结合实现快速捕获同步。实测数据验证了此接收机方案能在100 Mbit/s高传输速率的情况下能取得较好的超宽带信号接收效果。
A scheme Energy of detection receiver is presented, based on the transient characteristic of received UWB signal and PPM modulation scheme, this scheme adopts an energy detection circuit to detect UWB signal, this scheme combines the detection and synchronization acquisition. Theoretical analysis and experiment proves that the receiver can get good performance at the transmission rate of 100 Mbit/s.
