A Jitter-Robust High Data Rate Impulse Radio System with an Orthogonal Sinusoidal Correlation Receiver

摘要

In this paper, the Impulse Radio (IR) system of Pulse Position Amplitude Modulation (PPAM) using an Orthogonal Sinusoidal Correlation Receiver (OSCR) is proposed. PPAM combines Pulse Position Modulation (PPM) with Pulse Amplitude Modulation (PAM) to provide higher data throughput with low computational complexity. But the performance of PPAM is considerably sensitive to timing jitter. OSCR has remarkable tolerance against timing jitter, and thus can process PPAM signals with little SNR degradation. Simulation results show that the proposed system can provide higher data throughput while maintain the BER performance even when timing jitter is relatively large.
