Abstract
A demodulator cancels out the echo signal properties in the received signal to generate a primary signal, and cancels out the primary signal properties in the received signal to generate a separate echo signal. In addition, the demodulator may combine the primary signal and the echo signal in a comparison/combination operation to generate a third combined signal. Error correction operations may then be performed on all three of the primary signal, echo signal and combined signal, with the results of those error correction operations being used to select which of the three signals will serve as the transport stream.
