A new Doppler estimator based on fast power-control
Dacheng Yang · Journal of China Institute of Communications · 2003
A new simple Doppler estimator for mobile communication systems with fast power-control is proposed. Based on the fact that the faster channel variation leads to greater received power fluctuation,the scheme estimates the Doppler shift by measuring the fluctuation of the received signal power. The performance of the new scheme is simulated under single path Rayleigh fading channels and is compared with COV estimator. The results indicate that the new estimator has an acceptable estimation accuracy when the channel variation is not too fast.
