Simulator

In this lab, we carried out different digital modulation techniques like BPSK, DPSK and QPSK using CCS simulator. BPSK conveys data by changing, or modulating, two different phases of a reference signal. In DPSK, there is no absolute carrier phase reference, instead transmitted signal is itself used as phase reference. In QPSK two bits are modulated at once, selecting one of four possible carrier phase shifts.
