Abstract :
We present a novel, computationally simple method for interference suppression in an orthogonal-frequency division multiplexing system with multiple receive antennas. The algorithm estimates the power spectrum of the interference and noise using a low-order time-domain model, and uses a penalized-likelihood approach to adaptively choose the model order. Numerical examples illustrate the performance of our method.
