ITERATIVE RECEIVER DESIGN FOR SINGLE CARRIER CYCLIC PREFIX WITH CYCLIC DELAY DIVERSITY

Abstract

In this paper we consider a Single Carrier Cyclic Prefix (SCCP) modulation with Cyclic Delay Diversity (CCD). SCCP is an alternative to the multi-carrier transmission schemes such as Orthogonal Frequency Division Multiplexing (OFDM) and CCD is used to increase the frequency diversity.  We propose an iterative receiver which not only makes use of pilot symbols but also data symbols to increase the performance of the system.

The structure of this paper is as follows: the methods presented in section I,   section II provides the system model. The iterative receiver design is presented in Section III. The details of the Expectation Maximization (EM)-based channel estimation as well as the Minimum Mean Square Error (MMSE) with Soft Interference Cancelation (SIC)  algorithm are given in this Section. Simulation results are given in Section IV. Finally, Section V concludes the paper
