Abstract: Methods and apparatus for RF channel selection in a multi-frequency network. A method includes identifying selected local operations infrastructures (LOIs) and their neighboring LOIs, generating a neighbor description message (NDM) that identifies the selected LOIs and their neighboring LOIs and associates a descrambling sequence identifier with each RF channel of the selected LOIs and their neighboring LOIs, and distributing the NDM over the selected LOIs. An apparatus includes a message decoder to receive an NDM that identifies RF channels of a first LOI and neighboring LOIs, and wherein each RF channel is associated with a descrambling sequence identifier, and processing logic to detect content acquisition failures, determine a list of RF channels and their associated LOIs that carry desired content, and select a selected RF channel that is associated with a selected LOI that carries the most additional content among the associated LOIs.

Abstract: Systems and methods are provided for enhancing signal quality at receivers in a wireless network. In one embodiment, an antenna is selected from a subset of antennas based on a signal quality parameter such as received signal power or signal-to-noise ratio (SNR). In another embodiment, multiple antennas are applied to independent signal processing paths for the respective antennas where output from the paths is then combined to enhance overall signal quality at the receiver.
