Enhanced Alamouti decoding scheme for DVB-T2 systems in SFN channels
(
IEEE
, 2011 , Conference Paper)
The standard Alamouti space-frequency block code (SFBC) suffers from performance degradation when used over highly frequency-selective channels because the channel frequency response is not necessarily flat over the Alamouti ...
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 ...
A regularization approach to MSE analysis of OFDM under phase noise
(
Elsevier
, 2018 , Article)
Orthogonal frequency division multiplexing (OFDM) is widely used in broadband wireless communications systems because of its high resilience to frequency-selective fading and its low implementation complexity. Phase noise ...
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 ...
Digital baseband compensation of frequency-dependent joint TX/RX I/Q imbalance in beamforming MIMO 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 beamforming MIMO-OFDM systems. We derive the throughput-maximizing transmit/receive ...
SINR analysis for beamforming OFDM systems under joint transmit-receive I/Q imbalance
(
IEEE
, 2012 , Conference Paper)
In this paper, we derive an analytical expression for the subcarrier average SINR of a beamforming OFDM system in the presence of joint transmit-receive I/Q imbalance. The derived expression quantifies the impact of the ...
Reduced-complexity sparsity-aware joint phase noise mitigation and channel equalization in OFDM receivers
(
Elsevier B.V.
, 2018 , Article)
A major performance and complexity limitation in direct-conversion broadband wireless transceivers is the phase noise (PN) resulting from the inevitable imperfections in the fabrication process of the crystal oscillator. ...
A new WDM Application Response Time in WLAN Network and Fixed WiMAX using Distributed
(
IEEE
, 2014 , Conference Paper)
Worldwide Interoperability for Microwave Access (WiMAX) and Wireless LAN (WLAN) has emerged as a promising solution for last mile access technology to provide high speed internet access in the residential as well as small ...
