Abstract :
In this paper we present a system design that incorporates the functionalities of a digital modulator/demodulator along with controlling features such as symbol generation, filtering, modulation, demodulation, phase and timing recovery for QPSK and 16 QAM modulation schemes. It is concluded that for a BER of 10-5 an Eb/No of 13.5 dB and 9.5 dB is required for 16 QAM and QPSK respectively. Simulation and analysis of QPSK and 16 QAM modulator and demodulator is done on MATLABreg with real time implementation on TMS320C6713 digital signal processing (DSP) Kit.
