New I/Q Imbalance Modeling and Compensation in OFDM Systems With Frequency Offset
White Paper In this paper, a new model and compensation scheme of quadrature imbalance in analog I/Q OFDM transceivers is presented. Classically, the effect of I/Q imbalance is modeled by a cross-talk between pairs... [14 Apr 2007]
Joint Compensation of OFDM Transmitter and Receiver IQ Imbalance in the Presence of Carrier Frequency Offset
White Paper As OFDM is very sensitive to the carrier frequency offset, this distortion needs to be taken into account in the derivation and analysis of any IQ imbalance estimation/compensation scheme. In this paper... [11 Apr 2007]
Frequency Offset and I/Q Imbalance Compensation for OFDM Direct-Conversion Receivers
White Paper Two types of RF front-end imperfections in direct conversion receivers, namely frequency offset and I/Q imbalance, are addressed in this paper. This paper proposes a pilot-based scheme for both frequency... [27 Jul 2005]
Blind Frequency Offset Estimation for Overlap PCC-OFDM Systems in Presence of Phase Noise
White Paper The frequency offset estimator is designed based on the subcarrier pair imbalance (SPI) caused by frequency offset. This paper presents a technique for frequency offset... [26 Oct 2004]
