Abstract

This paper concerns developing a low complexity detector for spectrally-efficient Frequency-Division-Multiple-Access (FDMA) multiuser systems based on Continuous-Phase-Modulation (CPM). A class of tree-trellis-search based algorithms is proposed for joint/iterative detection and the complexity is further reduced employing a state-reduction technique based on mismatched filters. The proposed detector is evaluated in terms of minimum achievable Euclidean distance. Analytical and simulated results reveal that the proposed detector offers near optimum performance with significantly reduced complexity.
