Random-Multi-Branch Successive Interference Cancellation detection in single-user and multi-user MIMO environments

Abstract

This work focuses on a new methodology for use in a Multi-branch Serial Interference Cancellation (MB-SIC) type of MIMO detector. The proposed structure incorporates a low complexity ordering scheme and a variable amount of branches, whose number is controlled by a metric that reflects the quality of the current signal vector estimate. Single and multiple-user environments with both correlated and uncorrelated channels scenarios are considered. Bit error rate results, obtained through simulation, and complexity results, expressed in terms of the required number of flops per detected signal vector, are compared with the corresponding results of previously proposed MB-SIC schemes.

A wireless precoding technique for millimetre-wave MIMO system based on SIC-MMSE

“…Considering the mm-wave MIMO system with Distributed Antenna System (DAS) configuration, where, number of base antenna MB having k number of single antenna and N number remote radio heads. If the Q user also equipped with MU antenna, the receiving antennas, MR = MB + Nk ≥ QMU [19][20][21][22][23][24][25][26]. For Q user MU number flat fading channels, the MMSE pilot sk was considered before now can be rewritten as vectoral form, sk ∈ C M u ×1 .…”
