Quantised Massive Multi User Mimo Ofdm Uplink Using Combiners

Abstract

Coarse quantization at the Base Station (BS) of a massive Multi-User (MU) Multiple-Input Multiple-Output (MIMO) wireless system provides significant power and cost savings. Coarse quantization also enables significant reductions of the raw analog-to-digital converter data that must be transferred from a spatially separated antenna array to the baseband processing unit. This project investigates the uplink using combiner performance of a quantized massive MU-MIMO system that deploys Orthogonal Frequency-Division Multiplexing (OFDM) for wideband communication.
