Decentralized multiuser diversity with opportunistic packet transmission in MIMO wireless sensor networks
(
Elsevier
, 2013 , Article)
In this study, we consider a single-hop wireless sensor network where both the sensor nodes and the controller node have multiple antennas. We focus on single beam opportunistic communication and propose a threshold-based ...
I/Q imbalance in multiple beamforming {OFDM} transceivers: SINR analysis and digital baseband compensation
(
IEEE
, 2013 , Article)
In this paper, we start by investigating the impact of joint transmit-receive I/Q imbalance on the performance of direct-conversion beamforming OFDM transceivers. We derive a new analytical expression for the average ...
