General-purpose symbol rate and symbol timing estimation method by using multi-resolution analysis based on wavelet transform for multimode software radio
In this paper, we newly propose a general-purpose symbol rate and symbol timing estimation method for several modulation schemes by using multi-resolution analysis based on the wavelet transform in order to realize a software-reconfigurable radio transmission system. By using the proposed methods, we can estimate symbol rate and symbol synchronization timing with a common estimation method. In this paper we evaluate the estimation error under not only AWGN but also Rayleigh fading environments by utilizing several standard modulation schemes which are used for the Japanese Personal Digital Cellular (PDC), Japanese Personal Handy phone System (PHS) and Global System for Mobile communications (GSM).
