Doppler Compensation Based on Recursive Block for Wireless Communication

Chan-Ho Hwang and Ki-Man Kim
Abstract—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 conventional method.

Index Terms—Doppler frequency estimation, ambiguity function, Kay’s estimator, Rayleigh fading.
