Abstract

This paper presents the implementation of Phase Shift Keying (PSK) baseband modem on Digital Signal Processor (DSP). Different level of PSK modulation schemes were used which were 16-psk, 32-psk, 64-psk, 128-psk and 256-psk. MATLAB simulink software was used in this project to simulate the system. The system model consisted of modulator, demodulator, noise channel and channel coding. Noise channel that was used in the system is Addittive White Gaussian Noise (AWGN). After the simulation, a Matlab file was created to get the Bit Error Rate (BER) graph for all 6 level of modulation scheme. Then, the system was implemented on the DSP TMS320C6713 board. From the simulation, the result that was obtained was constellation point for all M-ary PSK before and after adding channel coding and AWGN. The BER graph that was obtained also follows the theory.
