A Group Sphere Decoder for the MIMO System

Abstract

Multiple Input Multiple Output (MIMO) system employs multiple antennas at both the transmitter and the receiver to improve the BER (Bit Error Rate) and system capacity. Different signal detection algorithms have different computational complexity and BER performance. In this paper, we provide a group sphere decoder (SD) in a MIMO wireless communication system. The group sphere decoder can further reduce the computational complexity for the conventional SD method.
