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...
