Paper Abstract

A new algorithm of frequency offset and symbol timing acquiring is derived for π/4-DQPSK signals in low signal-to-noise ratios (SNR). Comparing with some conventional schemes, this algorithm can joint frequency offset acquisition and symbol timing acquisition and needs fewer preamble date. It can work quite well at 3 dB SNR. Even if SNR is zero, it also gives an acceptable performance.
