A Robust Detector for Multicarrier Spread Spectrum Transmission Over Partially Jammed Channels.

Multicarrier spread spectrum (MC-SS) is an alternative to the conventional spread spectrum (SS) techniques that be- have significantly better when the system is subject to narrow- or partial-band interference. However, successful implementation of the optimum detector requires knowledge of noise and interference variance in each subcarrier band. In this paper, we propose a suboptimal detector for MC-SS that keeps the significant gain of MC-SS over the conventional SS, with a relatively low loss compared with the optimum MC-SS detector. Theoretical analysis and computer simulations that corroborate the theory are presented. [ABSTRACT FROM AUTHOR]
