Space-Time Coding in MISO-OFDM Systems With Implementation Impairments

White Paper Implementation of OFDM-based systems suffers from In-phase and Quadrature-phase (IQ) imbalances in the front-end analog processing. In this paper, the effect of IQ imbalances on an OFDM-based system with Alamouti coding is studied and an efficient... [10 Apr 2008]

On the Baseband Compensation of IQ Imbalances in OFDM Systems

White Paper Implementation of OFDM-based systems suffers from Inphase-Quadrature phase (IQ) imbalances in the front-end analog processing. In this paper, the effect of IQ imbalances on OFDM receivers is analyzed and system level algorithms to compensate for... [10 Apr 2008]

OFDM Systems With Both Transmitter and Receiver IQ Imbalances

White Paper The implementation of OFDM-based systems suffers from impairments such as In-phase and Quadrature-phase (IQ) imbalances in the front-end analog processing. Such imbalances are caused by the analog processing of the Radio Frequency (FS) signal and... [13 Apr 2007]

Joint Compensation of Transmitter and Receiver Impairments in OFDM Systems

White Paper The implementation of OFDM-based systems suffers from impairments such as in-phase and quadrature-phase (IQ) imbalances in the front-end analog processing. Such imbalances are caused by the analog processing of the Radio Frequency (RF) signal and... [11 Apr 2007]

Joint Compensation of OFDM Transmitter and Receiver IQ Imbalance in the Presence of Carrier Frequency Offset

White Paper However these systems suffer from In-phase/Quadrature-phase (IQ) imbalances in the front-end analog processing which may have a huge impact on the performance. In this paper the effect of both transmitter and receiver IQ imbalance under carrier... [11 Apr 2007]

Adaptive MIMO OFDM Receivers: Implementation Impairments and Complexity Issues

White Paper This paper illustrates the effect of In-phase and Quadrature-phase (IQ) imbalances on system performance. The impairments are caused by the analog processing of the received radio frequency (RF) signal and they cannot be efficiently or entirely... [29 Mar 2005]

Compensation Schemes and Performance Analysis of IQ Imbalances in OFDM Receivers

White Paper The implementation of OFDM-based physical layers suffers from the effect of In-phase and Quadrature-phase (IQ) imbalances in the front-end analog processing. In this paper, the effect of IQ imbalances on OFDM receivers is studied and system level... [23 Mar 2005]
