Sparsity-Aware Successive Interference Cancellation with Practical Constraints

Abstract

Abstract—This paper investigates new detection methods for low data-rate Machine Type Communication. Special attention is paid to uplink communication in networks where nodes are only active occasionally, which requires a joint activity and data detection at the receiver. This paper shows that a modified version of Successive Interference Cancellation is a viable approach for the detection of these low data-rate multi-user signals. The analysis is in the context of a hardware implementation, which we address particularly as we investigate the algorithmic complexity of the introduced algorithms. I.
