Compression of Spread Spectrum Signals on an Excessively Dispersive Channel.

Abstract

There are several new techniques for correcting time dispersive distortion of wideband and/or spread spectrum signals using signal processing capabilities which can be embedded into modern communications systems. These include adaptive channel equalization and in the case of spread spectrum signals, synchronous correlation, matched filtering and Rake processing. This paper shows several distinct advantages in the combination of matched filtering and Rake processing for handling dispersion of spread spectrum signals. Keywords include: Spread Spectrum; Rake; Pulse compression; Coherent detection; Adaptive equalizer; Linear equalizer; Channel coherence; and Signal processing.
