Practicable MIMO Capacity in Ideal Channels
— The impact of communications signal processing such as QAM modulations (instead of gaussian signals), finite block lengths (instead of infinitely long codes), and using simpl...

A Low-Complexity Detector for Large MIMO Systems and Multicarrier CDMA Systems
We consider large MIMO systems, where by `large' we mean number of transmit and receive antennas of the order of tens to hundreds. Such large MIMO systems will be of immense i...

A practical forwarding scheme for wireless relay channels based on the quantization of log-likelihood ratios
This paper considers a wireless relay network with one source, one relay, and one destination. We propose a low-complexity quantize-and-forward (QF) scheme in which the relay calc...

Effect of Word-length Precision on the Performance of MIMO Systems
Abstract—In this paper, we investigate the effect of quantization noise and roundoff errors involved in finite-precision (FP) signal processing on the performance of multiple-in...
