AbstractTesting radio communication systems in the field is time consuming and expensive since itis subject to uncontrollable phenomena such as weather time and test environment Therefore radio channel simulators are commonly used in the laboratory to allow lessexpensive and more repeatable system tests In this thesis we introduce a simulation modelfor Rayleigh fading channels based on the Basis Expansion Model BEM It exhibits firstand second order statistics of Rayleigh fading channels closely and in addition it can beused for simulating channels with different power spectral densities BEM may be used to represent each tap of time varying multipath channel with a linearcombination of a finite number of basis functions hence it is widely used in the estimationand equalization of doubly selective channels Existing works make use of a symbol bysymbol routine to estimate the expansion coefficients describing the channel within eachOFDM symbol Here in order to reduce the number of iterations in estimation process wepropose a K symbol by K symbol approach which exploits an extrapolation techniquebased on BEM to predict Channel Impulse Response over the next K 1 OFDM symbols This method provides faster data processing with less iteration in the estimation process thus increasing bandwidth efficiency
