An apparatus and method for receiving layered modulation signals is
disclosed. A typical method includes receiving a layered modulation
signal including an upper layer signal and a lower layer signal,
demodulating and decoding the upper layer signal from the received
layered modulation signal, estimating an upper layer amplitude factor and
an upper layer phase factor from the received layered modulation signal.
A substantially ideal upper layer signal is reconstructed from the
demodulated and decoded upper layer signal including matching an ideal
amplitude and an ideal phase by applying the upper layer amplitude factor
and the upper layer phase factor to the reconstructed ideal upper layer
signal. Finally, the reconstructed ideal upper layer signal is subtracted
from the received layered modulation signal to produce the lower layer
signal for processing.
