Design and implementation of real time wideband channel simulator

This paper describes the design and implementation of a DSP based real time wideband channel simulator. The simulator implementation uses a floating point (TMS320C6713) and a fixed point (TMS320C6416) DSPs. The simulator has 8 taps and baseband bandwidth of 20 MHz. It has flexibility to generate several channel models under varied environmental conditions. To validate the functionality of the simulator, the baseband data is applied to the simulator input and its output is statistically analyzed and the results are compared with those predicted analytically.
