Implementation and Bit Error Rate analysis of BPSK Modulation and Demodulation Technique using MATLAB
Journal Title: INTERNATIONAL JOURNAL OF ENGINEERING TRENDS AND TECHNOLOGY - Year 2013, Vol 4, Issue 9
Abstract
This paper presents the theoretical background of digital modulation and evaluate the performance of BPSK system with respect to Bit error Rate and finally implement Binary Phase shift Keying modulation technique in MATLAB. The main objective of any communication system is to receive the transmitted data accurately. There are lot digital modulation techniques that are well flourished in the communications field, selection of a suitable modulation technique for an application depends on many factors like Bit error rate, data rate, design complexity etc., one of the modulation techniques that is used in many areas of applications is the BPSK modulation. It is widely used due to its low BER and simplicity in design when compared to other modulation techniques. The BER for BPSK is performed using Matlab Graphical User Interface tool i.e., BERTool. The modulated signal is produced by modulating a carrier according to the binary code. The binary code taken here is the Gold code sequence. Such modulated signal is transmitted through AWGN channel. The resulting noisy modulated signal is demodulated using the BPSK demodulation technique. The complete system simulations are carried out in MATLAB R2008a and the same will be verified using Matlab Simulink environment.
