Abstract

This paper introduces a new framework of the multiple-input multiple-output (MIMO) detection in iterative receivers. Unlike the conventional methods processing with symbol lattice, we consider the delta symbol lattice, i.e., the difference between two arbitrary points in the symbol lattice. The inherent flexible, symmetric, and sparse properties of the delta lattice enhance the detection in both complexity and performance aspects. Consequently, we propose a delta-list MIMO (DL-MIMO) detection which separately exploits the channel information and the a priori information so that a soft-input soft-output sphere decoder is dispensable. Simulation results demonstrate this hardware-friendly DL-MIMO detection delivers nearly-optimal performance at affordable cost in a practical scenario.
