After the signal is sent from the transmitter, it will reach the receiver through the specific paths that are named channel. If the radio signal is sent, the paths which will pass through are named radio channel.
For a new mobile communication system’s emerging, the performance on the radio fading channel will be eva luated. So some channel models should be specified by the specific wireless communication system standard. These channel models are the base of performance eva luation and comparison. At present, some radio channel models are constructed according to the field measurement and stochastic process theory by the academic community, for examples, large scale fading model, small scale fading model and MIMO channel model for MIMO system. Some standard associates, e.g. ITU, also specify some channel models as the base for eva luation of mobile communication system. The exist channel models are the foundation of the thesis.
In the thesis, principle and features of radio channel are studied. Small large scale fading models are simulation with Matlab, and the results are also discussed.
