A new method for realization of fast bit rate estimation of PSK signal
Abstract：To solve the problem concerning the quick and accurate bit rate estimation of phase-shift keying（PSK） signals,a bit rate estimation method based on the discrete accumulation average of signals was proposed.Through setting the accumulation length and step for both carrier frequency estimation value and sampling rate,the peak values of accumulation average would appear at the phase mutation-points of the signals.After setting a certain threshold,the bit rate could be calculated quickly by searching the peak value points.Because only the addition and less multiplication operations are carried out in the proposed algorithm,a large number of multiplication operations in the traditional instantaneous auto-correlation algorithm can be avoided.In addition,the proposed algorithm exhibits the characteristics of high speed and easy engineering realization.The results of simulation tests show that the proposed algorithm has certain effectiveness and accuracy,and exhibits the stronger anti-noise property compared with the instantaneous auto-correlation algorithm.
