—The Doppler effect and fading that has time
variance affect the wireless communication reliability.
Especially, the Doppler effect reduces the transmission
efficiency. Thus, we need to recognize the channel state and
apply it to communication technique for increasing transmission
efficiency. In this paper, we present the frame recursive
modulation and demodulation method using ambiguity function
and Kay’s estimator to estimate the Doppler frequency.
Furthermore, we conducted the simulation in environment with
Rayleigh fading and the Doppler effect. When the channel
coding technique was not used, the bit error rate of the proposed
method was improved maximum 17 % compared with
—Doppler frequency estimation, ambiguity
function, Kay’s estimator, Rayleigh fading.
