Analytical performance evaluation of Base Station cooperation systems using SC-FDE modulations with iterative receivers

Abstract

BS (Base Station) cooperation architectures provide significant capacity gains, since they allow users in adjacent cells to share the same physical channel. By employing iterative frequency-domain receivers that combine signals received by different BSs we can effectively separate the signals associated to different MTs. In this paper we consider the use of SC-FDE (Single-Carrier with Frequency-Domain Equalization) schemes in the uplink of BS cooperation architectures where the receiver is based on the IB-DFE (Iterative Block Decision Feedback Equalization) concept and we present a simple and accurate analytical model for obtaining the corresponding BER performance.
