ABSTRACT:
This invention provides a digital data communication system which is able to combine two data streams from two data sources at the transmitter end, transmit the data and then separate the streams to two data ports at the receiver end. The system makes use of QAM or PSK modulation, and synchronization between the transmitter and the receiver is maintained by changing the radial component of every other transmitted symbol. At the receiver end the radial components of every other symbols are correlated to detect loss of synchronization. Once such a loss is detected, the receiver is adapted to self-synchronize itself with the transmitter.
