Joint Modulus Zero-Forcing MIMO Detector

Abstract

We propose an improvement over a modulus zero-forcing (MZF) detector proposed earlier in [1] for multi-input multi-output (MIMO) detection, namely, the joint MZF (JMZF) detector. The MZF detector provides better detection-performance than a traditional ZF detector through preserving controllable interferences, which are mitigated later by nonlinear modulus arithmetic operation. However, the MZF detector has a constraint that the effective MIMO channel after modulus operation is diagonal, which yields separate detections on different transmit layers and is suboptimal. In this paper, we propose the JMZF detector by considering a general effective channel which can further boost the detection-performance.
