CARRIER FREQUENCY OFFSET

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 …

Code-aided channel tracking and frequency offset-phase noise elimination for multicarrier systems

In this contribution, we propose a novel code-aided channel tracking and carrier frequency offset (CFO) and/or phase noise (PN) estimation algorithm for orthogonal frequency-division multiplexing (OFDM) systems. Starting from the maximum-likelihood …
