A USRP-based experimental testbed for OFDM systems impaired by I/Q imbalance
( IEEE , 2013 , Conference Paper)In this paper, an experimental testbed for packet based OFDM systems is proposed using USRP RF front-ends. I/Q imbalance estimation and compensation algorithms are implemented at the receiver by manually injecting I/Q ... -
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 ... -
Modelling and compensation of frequency-dependent I/Q imbalance in multiple beamforming OFDM transceivers
( IEEE , 2012 , Conference Paper)In this paper, we investigate the effects of asymmetric frequency-dependent joint transmit-receive I/Q imbalance on the performance of multiple beamforming MIMO OFDM systems. We derive the throughput-maximizing TX/RX ...
