Comparing Throughputs of 2×2 Spatial Multiplexing MIMO Systems with and without CSI at the Transmit Side in Rich Isotropic Multipath Environments

Paper i proceeding, 2014

Multiple-input multiple-output (MIMO) systems are attracting more and more attention due to the need of high spectral efficiency. Simple yet accurate throughput models are highly desired for studying the MIMO performance. MIMO throughput models based on the threshold receiver have been studied in [1], [2]. Specifically, a single-input multiple-output (SIMO) throughput model based on the concept of the threshold receiver was presented in [1]. The SIMO throughput model was extended to MIMO systems with full spatial multiplexing in [2], where only the open-loop configuration is studied.
