Comparison of model and performance of BPSK, QPSK and OQPSK / Nurul Rashidah Abu Samah

Digital modulation is a process of transforming a digital symbol to a signal suitable for transmission via a communication channel. Binary Phase Shift Keying (BPSK), Quadrature Phase Shift Keying (QPSK) and Offset Quadrature Phase Shift Keying (OQPSK) are the type of digital modulation under Phase S...

description Digital modulation is a process of transforming a digital symbol to a signal suitable for transmission via a communication channel. Binary Phase Shift Keying (BPSK), Quadrature Phase Shift Keying (QPSK) and Offset Quadrature Phase Shift Keying (OQPSK) are the type of digital modulation under Phase Shift Keying family. QPSK and OQPSK modulation technique is the most widely modulation scheme used in the digital communication system such as wireless and satellite. It is due to their high performance in Bit Error Rate and bandwidth efficiency. This paper analyzes the simulation model design and performance between BPSK, QPSK and OQPSK. The model of BPSK, QPSK and OQPSK has been designed and simulated in Matlab using Simulink. The methodology used in this paper is by designing and analysing the simulation result between BPSK, QPSK and OQPSK in term of their performance. The result shows that the OQPSK is much better compare to the BPSK and QPSK for higher data rate transmission due to its delay in quadrature component make the phase shifted can only be 0° and ±90° can reduce the amplitude fluctuation in QPSK.
