摘　　要：Chirp-UWB具有发射功率低、抗干扰能力强、传输距离远等优点,非常适合远距离UWB应用。针对接收机中的Chirp调制信号解调,提出了一种基于PLL解调Chirp-UWB信号的方案。试验表明,采用PLL解调的Chirp信号具有灵敏度高、信噪比高、电路易于实现、成本低、可扩展性强等优点。Chirp-UWB has the advantage of low transmission power, highly in anti-jamming ability and long distance transmission. It is very suitable for long distance transmission for UWB communication systems. In this paper, a solution based on PLL demodulation in the Chirp-UWB receiver is proposed. It proves that the receiver based on PLL demodulation has the advantages of high sensitivity, high SNR, simple circuit, low cost and expansibility.
