Abstract: Detecting the presence of a television signal embedded in a received signal including the television signal and noise. Either first-order or second order cyclostationary property of the signals may be used for their detection. When the first-order cyclostationary property is used, the received signal is upsampled by a factor of N, a synchronous averaging of a set of M segments of the upsampled received signal is performed, an autocorrelation of the signal is performed; and the presence of peaks in the output of the autocorrelation function is detected. When the second order cyclostationary property of the signal is used, the received signal is delayed by a fixed delay (symbol time), the received signal is multiplied with the delayed version, and a tone (single frequency) in the output is detected.

Abstract: A multi-band communication system includes a plurality of transmit channels, where each transmit channel transmits data streams through a single sub-band, and a plurality of receive channels, where each receive channel receives data streams of a single sub-band. According to one embodiment of the invention, each transmit channel and its respective receive channel are configured with a different set of channel codes to encode and decode the data. The set of channel codes is determined by an adaptive modulation coding controller based on a condition of the link between a transmit channel and a receive channel.
