Abstract

Two closely related iterative receivers for mitigation of both intra- and inter-cell interference are considered for HSDPA in UTRA-TDD. The first receiver is based on coherent detection with pre-whitening with respect to the spatio-temporal structure of the interference. The second receiver is based on interference suppression via deterministic least-squares filtering. The performance of the receivers is evaluated via system-aware link-level simulations of 2-cell indoor and 7-cell urban scenarios. Performance improvements over the conventional RAKE receiver are reported in the form of BER statistics.
