Filter Centered Nonisotropic Fading Channel Archetypal For Wireless System Assessment

Ashish Francis, Riboy Cheriyan

In this paper filter based nonisotropic fading channel model for evaluating mobile radio communication is been proposed, fading occurs due to the multipath propagation of the signal. For assessing the performance and characteristics of a wireless communication system the channel has to be modelled in laboratory settings, the channel model can be hardware or software based. The development of the wireless systems becomes easier and faster when the channels are modelled in software platform as the channel models can be easily reorganized by altering the channel parameters. Channel is nonsiotropic if the scattering is non uniform. The channel model is designed based upon the filter approach rather the common sum of sinusoid method. The design is developed in VHDL and the different FPGA platforms for the channel model is studied.
