Frame detection and timing acquisition are challenging tasks in orthogonal frequency-
division multiplexing systems plagued by narrowband interference (NBI). Most existing …

We consider an OFDM system employing bit-interleaved coded-modulation (BICM) and
investigate the problem of reliable data detection in the presence of narrowband …

Many acoustic channels suffer from interference which is neither narrowband nor impulsive.
This relatively long duration partial band interference can be particularly detrimental to …

In this paper, we propose a spectrum sensing based joint rate and power allocation scheme
