Abstract
In this paper a review of the Pre-FFT Equalization technique is presented with a particular focus on 4G applications. The essential concepts and motivations for the use of this technique are first presented. Subsequently, previous research of the topic both by the authors and others is reviewed. In particular, methods for implementing the Pre-FFT Equalizer itself and for adapting it are reviewed in detail. The issue of noise amplification and the use of Channel State Information in the COFDM system to mitigate this phenomenon are also discussed. Application of a Pre-FFT Equalizer to a possible, COFDM based, 4G standard is then discussed and software simulations used to demonstrate the benefits that can be achieved by a Pre-FFT Equalizer in a 4G system.
