Abstract
In a receiver for multiplexed QAM/PSK signals which have been radial amplitude modulated for synchronization, an error signal is generated by each received signal to the corresponding ideal point as mapped in the complex plane. A synchronizing signal is generated and synchronized by the error signal and is used for both demultiplexing, and amplitude demodulating the signal.
