| Summary: | In wireless communication systems, the phenomenon of multipath fading is unavoidable. In order to know the performance of this communication system, a software or hardware prototype of multipath fading channel is needed to approach the actual channel condition. In this final project, the author is interested in developing a hardware prototype of multipath fading channel using TMS320C6713 <br />

DSK. The first thing to do is to design the Rayleigh fading signal generation. The method used involves an IIR filter and an interpolator. Then, it is simulated by using MATLAB, a simulation in C language using CCS, which is then implemented into TMS320C6713 DSK The implementation is divided into a real-time and a non real-time. The realtime <br />

implementation uses a signal generator as input signals and the non real-time implementation uses BPSK and OFDM communication system in its processing signal. From the test, the author found that the pdf histogram of Rayleigh fading signal has a distribution that approximates the theoretical values. From the calculation of channel parameters, the fading signals have the characteristics of slow fading and frequency-selective fading. |
