Abstract: In an embodiment, an apparatus includes: a modulator to modulate a first packet according to rate control information; a physical circuit to transmit the modulated first packet according to power control information; and a dynamic adaptation circuit, for the first packet, to provide the rate control information and the power control information of a first modulation and power pair stored in a first energy map.

Abstract: 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.

Abstract: An apparatus includes a first integrated circuit (IC) that includes a first radio-frequency (RF) circuit to process RF signals, a first antenna port to couple to one or more antennas, and a first switch integrated in the first IC and coupled to the first antenna port. The apparatus further includes a second IC that includes a second RF circuit to process RF signals, a second antenna port to couple to the one or more antennas, and a second switch integrated in the second IC and coupled to the second antenna port.
