Abstract:
A communications device includes aspects for improving reception of transmissions with first-adjacent co-channel interference signals corresponding to digitally-modulated side-bands of in-band on-channel (IBOC) broadcasted signals. The communications device may include a radio frequency (RF) signal-reception circuit including two RF-signal paths driven in response to signals received via at least two respective antennas, and configured to respond to signals carried in the respective RF-signal paths by providing pre-processed RF output signals. The communications device may further include a beam-forming circuit driven in response to signals received at the at least two respective antennas and configured and arranged to facilitate first-adjacent interference cancellation (FAC). The communications device can also include an interference-cancelling circuit configured and arranged to reduce the first-adjacent co-channel interference signals by combining a beam-forming output signal provided by the beam-forming circuit with the pre-processed RF output signals as part of a maximum ratio combining (MRC) process.

Claim (Index 8):
A method for improving reception of transmissions with first-adjacent co-channel interference signals corresponding to digitally-modulated side-bands of in-band on-channel (IBOC) broadcasted signals, the method comprising:\n generating at least two radio frequency (RF)-signal paths in response to signals received via at least two respective antennas; providing pre-processed RF output signals for each of the at least two RF-signal paths using respectively-associated front-end circuits including analog-to-digital converter and signal-processing circuitry; in response to the signals received at the at least two respective antennas, facilitating first-adjacent interference cancellation (FAC) by:\n providing a beam forming for first adjacent cancellation (BFFAC) signal as a function of the first-adjacent co-channel interference signals; \n using a statistically-based analysis to weigh or assess a likelihood of the BFFAC signal indicating the first-adjacent co-channel interference signals are significant; and \n providing a beam-forming output signal in which weighting for noise-cancellation is provided for in response to the statistically-based analysis; and \n reducing the first-adjacent co-channel interference signals by combining the beam-forming output signal with the pre-processed RF output signals using the statistically-based analysis of the BFFAC signal to compensate for the first-adjacent co-channel interference.
