On Some Unifications Arising from the MIMO Rician Shadowed Model [PDF]
, 2015 This paper shows that the proposed Rician shadowed model for multi-antenna communications allows for the unification of a wide set of models, both for multiple-input multiple-output (MIMO) and single- input single-output (SISO) communications.

Impact of Channel Correlation on Different Performance Metrics of OSSK-Based FSO System [PDF]
, 2020 In this paper, we study the impact of correlation on the bit error rate (BER) and the channel capacity of a free-space optical (FSO) multiple-input-multiple-output (MIMO) system employing optical space shift keying (OSSK) over a fading channel.

Bootstrap frequency equalisation for MIMO wireless systems [PDF]
, 2003 The paper reports on a new class of equalisation/detection for wideband multiple input-multiple output (MIMO) communications systems. The proposed scheme is somewhat akin to a multi-carrier MIMO system, and more precisely, builds upon a single carrier ...

MIMO detection in analog VLSI [PDF]
, 2006 In this paper we propose an analog VLSI approach to maximum a posteriori (MAP) detection in multiple-input multiple-output (MIMO) systems. This detector can be seen as an extension of the well known analog decoding concept for error correcting codes, as ...
