Abstract
An accurate assessment of the performance of a newly developed radio system can be done through repeated tests of the system over an actual channel. When comparison is to be made between two or more systems over a real channel, they must all be tested simultaneously. The channel characteristics and transmission conditions vary uncontrollably. Hence tests can`t be repeated at other times. Moreover it is not possible to test a system repeatedly for the same channel conditions. The computer simulation of channel model using C++ on Linux shows good degree for accuracy between input and output. The signal to noise ratio for different channel conditions can be calculated easily for rating the channel. The most challenging technical problem being faced by communication system engineers is fading in a mobile environment. The term fading refers to the time variation of received signal power caused by changes in the transmission medium or path(s). In a fixed environment, fading is affected by changes in atmospheric conditions, such as rainfall. But in a mobile environment, where one of the two antennae is moving relative to the other, the relative location of various obstacles changes over time, creating complex transmission effects.
