Error rate prediction for high data rate short range systems

Present mobile radio services offer primarily voice communication to customers roaming within large cell topographies. Typically these systems do not require large bandwidths and offer little or nothing in the way of data based services with the result that they operate with bit error rates as high as one in one thousand. However, in recent years there has been a trend towards more spectrally efficient, small cell, high data rate systems and a growing demand for a new type of service offering very high data rates for indoor wireless LAN applications. In this paper we present a model which predicts propagation characteristics for given small cell environments and subsequently uses the propagation data to analyse the radio link performance for a variety of system designs. In order to achieve very accurate high data rate transmission the benefits of linear modulation combined with techniques such as diversity, frequency hopping and pulse shaping are investigated.
