    Abstract

    Inter symbol interference is a well-known problem in mobile communications. This type of interference can be reduced by an adaptive equalizer. For the reduction of ISI in a mobile indoor environment complying to DECT, an adaptive equalizer has to be implemented in the mobile unit. Hence the extra required power consumption should be minimal. Therefore, the computational complexity of the equalizer algorithm is important. The purpose of the research presented in this paper, is to investigate the implementation of an adaptive equalizer in finite precision arithmetic. Scaling methods are used to reduce the wordlength to the mimimum value at which the algorithm still has the same ISI performance as with floating point computation. We present simulated scatter diagrams of different channels for Fast Transversal Filter (FTF) based equalizer structures.
