Abstract
The Doppler effect and fading that has timevariance affect the wireless communication reliability.Especially, the Doppler effect reduces the transmissionefficiency. Thus, we need to recognize the channel state andapply it to communication technique for increasing transmissionefficiency. In this paper, we present the frame recursivemodulation and demodulation method using ambiguity functionand Kay’s estimator to estimate the Doppler frequency.Furthermore, we conducted the simulation in environment withRayleigh fading and the Doppler effect. When the channelcoding technique was not used, the bit error rate of the proposedmethod was improved maximum 17 % compared withconventional method.
