摘要： Systems and methods are disclosed for rapid detection of digital content within received radio frequency (RF) signals. The disclosed embodiments digitize received RF signals and apply a sliding window average to subsampled complex magnitudes for the digital samples to generate subsampled magnitude values. The subsampled magnitude values are then collected over a small number of symbols for the digital content, and the results are analyzed to determine whether or not digital content is present with the received signals. For example, multi-symbol histograms and magnitude ratios determined over multiple symbols can then be utilized to make the determination of whether digital content is present in the received signals. The resulting detection determination can be utilized further to control operations of systems utilizing the disclosed embodiments. The disclosed embodiments can be used, for example, to detect the presence of HD (High Definition) Radio digital content within broadcast channels.

摘要： Systems and methods are disclosed for time-domain diversity combining of radio frequency (RF) broadcast signals. Two channelized quadrature (I/Q) signals are generated by different tuner circuitry coupled to two different antennas, are converted to frequency-domain signals, and are used to generate frequency-domain diversity weighting signals. The frequency-domain diversity weighting signals are then converted to time-domain weights and applied to the channelized I/Q signals. The weighted and channelized I/Q signals are then combined in the time-domain to provide a time-domain diversity combined signal. The resulting combined signal can be further processed, as desired, such as by using a demodulator to generate demodulated output signals. Disclosed methods and systems can be applied to a variety of receiver systems configured to receive RF broadcast signals.
