| Abstract: | The blind estimation algorithm of Doppler frequency suitable for telemetry systems involving additional white Gaussian noise(AWGN)channels is proposed in this paper.The choice of algorithm parameters is discussed,and factors influencing the estimation accuracy are analyzed.This algorithm behaves good performances over a large Doppler frequency offset for different modulated signals with different baud rates. |
