EXPECTATION-MAXIMIZATION ALGORITHM
Novel data detection and channel estimation algorithms for BICM-OFDMA uplink asynchronous systems in the presence of IQ imbalance
The problem of channel estimation and in-phase/quadrature-phase (IQ) imbalance is one of the main challenges that has to be faced by uplink transmission in orthogonal frequency division multiple access (OFDMA) systems. The previously reported …
