摘要
文章将相位调制与脉位调制技术相结合,提出了一种应用UWB通信系统的新颖调制技术-QPPM。在解调过程中,它使用2个模板信号做相关检测,一个解调位置,另一个解调相位,算法实现简单;仿真实验表明,在加性高斯白噪声信道和瑞利信道中它比2-PPM有较低的误码率性能,同时获得了双倍的传输速率。
The paper presents a novel modulation technique through combining BPSK and PPM for ultra-wideband communication. It uses two template signals for correlation demodulation, one for the position, and the other for the phase. The algorithm can be easily implemented. The experiment results show that the proposed technique has lower BER performance in comparison with 2-PPM in the AWGN channel and the Raleigh channel and it yields double data throughput.
