Implementation of Digital Communication System on DSK TMS320C6713
Keywords:
Digital Modulation, AWGN, Rayleigh, BER, DSK TMS320C6713Abstract
Communication system using digital modulation has been used widely on telecommunication system nowadays, including voice communication, video or data. In this research author make a system implementation digital communication using modulation techniques ASK, FSK, BPSK, dan QPSK that passed into AWGN channel (Additive White Gaussian Noise) then added Rayleigh on DSK device (Digital Signal Processing Starter Kit) TMS320C6713 type. Furthermore, the designed system was evaluated. The evaluation of modulator signal output was in accordance with characteristic each modulation, but the received information signal was different from the sent information signal. BER performance that resulted from each system was fluktuatif. Both of these were caused by the AWGN channel and Rayleigh and the system did not use the signal quality improvement techniques of received information. The most efficient system in terms of memory usage on TMS320C6713 DSK is a system with FSK modulation, with a value of 1.15719697%. While most large systems use a memory is ASK communication systems with a value of 1.191666667% efficiency.
