Receiver cooperative MIMO-OFDM capacity with quantization error and spatial correlation

Abstract

Let us consider that space division multiplexing (SDM) signal is transmitted at a base station (BS) with a number of antennae to mobile terminals (MTs) with fewer antennae. It will be intractable for a MT to demultiplex the SDM signal by space filtering in the case of less degrees of freedom at the MT. Receiver cooperative multiple-input and multiple-output (RC-MIMO) is applied to demultiplex the SDM signal with the enhancement of degrees of freedom at the MT by sharing the other SDM signals received at the surrounding MTs with pulse code modulated radio over higher-frequency radio (PCM-RoHR). In this paper, we show the capacity of RC-MIMO with PCM-RoHR by taking its fading spatial correlation and quantization error into consideration with numerical analysis.
