ABSTRACT
This paper presents the theoretical background
of digital modulation and evaluate the performance of the 32-PSK system with
respect to Bit Error Rate and finally implement a 32-ary Phase Shift Keying
modulation technique in MATLAB. The key objective of any communication system
is to obtain the transmitted data accurately. Many digital modulation
techniques have thriven in the communications field, choosing a suitable
modulation technique for an application depends on many factors like Bit error
rate, data rate, design complexity etc. The BER for 32-PSK modulated signal is
performed using MATLAB Graphical User Interface tool. The modulated signal is
transmitted through an AWGN channel. The resultant noisy modulated signal is
demodulated using the BPSK demodulation technique. An outright comparison was
made and conclusions drawn after the various BER and Eb/No relationships were
established. The complete system simulations are carried out in MATLAB R2015b.
Keywords: Simulation, BER, AWGN, 32-PSK, MATLAB
