Achievable rates of nonlinear MIMO systems with noisy channel state information

Abstract

Multiple input multiple output (MIMO) communication systems that employ nonlinear detectors, i.e., amplitude-only or phase-only detectors, where first introduced. Such systems are low-complexity and low-power alternatives to legacy MIMO systems in applications, e.g. sensor networks, where low power consumption and low cost are very stringent constraints. This work extends the achievable rates study presented, to cover the case where the channel estimation at the receiver contains an additive Gaussian noise term.
