ChSim, created at University Paderborn, is an OMNeT++ simulation model which generates channel state values (1/attenuation) in dB for a single wireless cell. This cell includes one base station and N terminals, each terminal can have M unidirectional links to the base station. For each of these links channel state values can be generated in the time and frequency domain. These values can be written to a file or processed in own simulation modules. The simulator includes several mobility and channel models.
Ideas and code from ChSim has been used in the development of MiXiM.
