Abstract
A system and method for low complexity frequency hopping simulation for communication device performance testing is disclosed. A baseband and channel model combination in a baseband processing module () of a testing system () reduces the required number of computations while retaining accuracy. A simulated channel is generated () with a bandwidth required for frequency hopping, and the hopping is simulated by shifting () the channel () instead of the signal (). Signal attenuation by the shifted channel () is modeled in the baseband processing module (), and the resulting simulated signal () is then up-sampled () to the proper frequency for output to the test device ().
