Abstract

Designing high performance multi-mode MIMO detectors is the key to successful implementation of multiple-input multiple-output (MIMO) communication systems. As an attempt to address this issue, this paper presents a VLSI architecture for implementation of depth-first sphere decoding algorithm that can operate in multiple operating modes. To demonstrate the effectiveness of the proposed architecture, a configurable sphere detector has been implemented that can support 2times2/3times3/4times4 BPSK/QPSK/16-QAM MIMO systems.
