Title:	Performance Analysis of a Fixed-Complexity Sphere Decoder in High-Dimensional MIMO Systems
Authors:	Luis Barbero, John Thompson, University of Edinburgh, United Kingdom
Abstract:	The performance of a new detection algorithm for uncoded MIMO systems based on the complex version of the sphere decoder is analyzed in this paper. The algorithm performs a fixed number of operations to detect the signal, independent of the noise level. Simulation results show that it can be applied to high-dimensional MIMO systems presenting a very small BER degradation compared to the original sphere decoder. In addition, its deterministic nature makes it suitable for hardware implementation.
