Fundamental diversity, multiplexing, and array gain tradeoff under different MIMO channel models
Following the seminal work of Zheng and Tse on the diversity and multiplexing tradeoff (DMT) of MIMO channels, in this paper we introduce the array gain to investigate the fundame...

Optimization of Training and Scheduling in the Non-Coherent SIMO Multiple Access Channel
— Channel state information (CSI) is important for achieving large rates in MIMO channels. However, in timevarying MIMO channels, there is a tradeoff between the time/energy spen...

Fixed-Complexity Soft MIMO Detection via Partial Marginalization
Abstract--This paper presents a new approach to soft demodulation for MIMO channels. The proposed method is an approximation to the exact a posteriori probability-per-bit computer....

MIMO Diversity in the Presence of Double Scattering
The potential benefits of multiple-antenna systems may be limited by two types of channel degradations--rank deficiency and spatial fading correlation of the channel. In this paper...
