Abstract
A first phase change is introduced to an analog signal based on a symbol specified by a data signal, where the symbol is one of a plurality of symbols in a symbol constellation. The analog signal is added to the data signal to form a combined signal which is transmitted over a communication channel that introduces a channel phase change to the analog and data signals. After transmission through the communication channel, the combined signal comprises a phase changed analog signal and a phase changed data signal. A received symbol is specified by the phase changed data signal, and a phase shift is introduced to the phase changed analog signal based on the identity of the received symbol.
