The prediction-error filter (PEF) is introduced as a means for mitigating the NBI in the time-domain prior to demodulation. Expand

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

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

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

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

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

This dissertation examines the effect of severe narrowband interference on wireless communication systems, where convergence is considered in terms of the bit error rate (BER). Expand
