We present CPM for TTC signals, since it provides low spectral occupancy and is suitable for power- and bandwidth-limited channels. Here, the Baum-Welch (BW) algorithm is modified to estimate the channel parameters. We investigate the performance of TTC/CPM for 16-CPFSK over AWGN and Rician channels for different frame sizes, in the case of ideal channel state information (CSI), no CSI, and BW estimated CSI. © 2005 IEEE.eninfo:eu-repo/semantics/closedAccessContinuous-phase modulation (CPM)MAP estimationParameter estimationRician channelArticle42397403Q1WOS:000228033400011Q12-s2.0-1714439836710.1109/TWC.2004.840214
