Abstract: A system and method for detecting the preamble of a wireless packet is disclosed. The system utilizes one or more received fragments as inputs to a correlator, forming correlator content inside the correlator memory. After every sample from the received fragment is provided to the correlator, the correlator then compares the correlator content to a known pattern pre-programmed as a set of correlation coefficients. The correlation coefficients may not align with the correlator content because the symbol boundaries are not known a-priori. By cyclic rotation of the correlation coefficients relative to the correlator content, or cyclic rotation of the correlator content relative to the known correlation coefficients, a match with one or more preamble symbols may be found. This technique may be used to reduce power during the preamble detection process. Alternatively, this technique can also be used for antenna diversity, multi PHY and multichannel applications.

Abstract: Antenna elements support RF communication over a communication link using frequency channels, RF processing circuits, and configuration circuitry to apply a selected configuration. Each configuration identifies processing circuit to antenna element couplings, and which frequency channel is allocated to each RF processing circuit.

A selection policy selects a configuration for a current link state, and then a new reward is observed that is dependent on how the selected configuration alters a chosen performance metric for the communication link.
