In this letter, an algorithm that estimates one of the most important channel parameters, maximum Doppler frequency, f_D, is proposed. The algorithm uses phase variations of received pilot signals, which is strongly related with f_D in a fading environment. In addition, a phase variation measurement method for binary phase shift keying (BPSK) modulated signals is also proposed and it makes possible to estimate f_D from BPSK modulated information signals as well as unmodulated pilot signals. The results show that the proposed algorithm is very simple and shows good performance over wide Doppler frequency range.
