A Multi-Synchronous Reference Algorithm of Symbol Rate Estimation
Wei Liu, Yao Yuan-cheng, Mingwei Qin · 2011
In non-cooperative communication system, symbol rate is a crucial part of parameter estimation. The symbol rate estimation is deeply researched by the use of Continuous Wavelet transform (CWT). And a new multi-synchronous reference(MSR)approach is proposed to extract precise symbol rate of M-ary Phase Shift Keying (MPSK) signal. The value of MSR algorithm is focused on lower signal-to-noise rate (SNR) scenarios. Simulation shows that both the performance of anti-noise and the accuracy are much higher than traditional algorithms.
