OFDM Channel Estimation in the Presence of Frequency Offset, IQ Imbalance and Phase Noise
2007
IEEE International Conference on Acoustics, Speech and Signal Processing - ICASSP '07
OFDM systems are susceptible to receiver impairments like frequency offset, IQ imbalance and phase noise. In this paper, OFDM channel estimation in the presence of these impairments is studied, and an iterative algorithm is proposed to jointly estimate the channel coefficients and the impairment parameters. It is shown by computer simulations that the algorithm performs close to its associated Cramer-Rao lower bound.
