A slot timing detection method with multiple-symbol differential detection for MDPSK burst signals

Abstract

This paper presents a slot timing detection method with multiple-symbol differential detection (MSDD) that offers improved transmission efficiency and mitigates the performance deterioration caused by carrier frequency offset. The method is applicable for burst wireless systems with short burst M-differential phase shift keying (MDPSK) signals and low symbol rates, which suits radio-frequency identifications (RF-IDs) or other ubiquitous wireless applications. Computer simulations show that the proposed method improves slot timing detection and error rate performances and yields robust demodulation of data symbols against carrier frequency offset.
