This project is proposed, transmitted and received using Quadranture Phase Shift Keying. The data will be transmitted via coaxial cable. In the transmitter the signals differ by phase shift and the receiver must be demodulate and decode the data. In this project used 64 kbps data stream modulated with 512 kHz carrier signal and used 256 kHz pilot signals. The advantage of QPSK is the signals have a single frequency, no DC component, easy to demodulate and clock recovery.
