Narrowband interference mitigation in BICM OFDM systems
TLDR
This paper examines the performance of a bit-interleaved coded modulated (BICM) OFDM system using the PEF and BPSK modulation in the presence of narrowband interference. Expand

Mitigation of narrowband interference using adaptive equalizers
TLDR
In the case of severe narrowband interference, the decision-feedback equalizer requires a convergence time that makes it unsuitable for some types of communication systems. Expand

Mitigation of unknown narrowband interference using instantaneous error updates
TLDR
Nonlinear effects of the normalized least mean square (NLMS) algorithm are studied in the presence of multipath and severe narrowband interference, for applications where there is no direct reference for the interfering signal. Expand

A Two-Stage Approach for Improving the Convergence of Least-Mean-Square Adaptive Decision-Feedback Equalizers in the Presence of Severe Narrowband Interference
TLDR
This paper investigates the introduction of an LMS prediction-error filter (PEF) as a prefilter to the equalizer and demonstrates that it reduces the convergence time of the two-stage system by as much as two orders of magnitude. Expand

Initialization Techniques for Improved Convergence of LMS DFEs in Strong Interference Environments
TLDR
We have investigated two different computationally efficient techniques for obtaining an estimate of the Wiener weights for the initialization of the decision-feedback equalizer (DFE) from estimates of the correlation matrices in the presence of severe narrowband interference. Expand

Interference Rejection and Management
Abstract : We consider interference suppression in several wireless communication systems. The first topic treated is self-interference encountered among cooperating systems, for example, theExpand
