摘要: An arrangement of interleavers allocates bits from an input symbol across sub-symbols transmitted via sub-carriers of multiple orthogonal frequency division multiplex (OFDM) carriers. The input bits are allocated in a fashion to provide separation across subcarriers, and rotation of sub-symbols across the OFDM carriers provides additional robustness in the present of signal path impairments.

摘要: A method for wireless communication begins by determining whether legacy devices are within a proximal region of the wireless communication. The method continues, when at least one legacy device is within the proximal region, formatting a frame to include: a legacy preamble; a signal field; an extended preamble; at least one additional signal field; at least one service field; an inter frame gap; and a data field.

摘要: Classifier for communication device. A communication device includes a classifier and a number of PHY (physical layer) receivers communicatively coupled thereto that enable the communication device to process various received signal types. Each of the PHY receivers is operable to perform pre-processing of a received frame (or packet) of data and to calculate a confidence level indicating whether the received frame is intended for that particular PHY receiver; this pre-processing does not involve processing (e.g., demodulation and/or decoding) of the received frame. Those PHY receivers having sufficiently high confidence levels assert claims to the classifier for the received frame. The classifier is operable to arbitrate between competing claims by 2 or more PHY receivers and to ensure that the received frame is provided to the PHY receiver for which it is intended.

摘要: A receiver front end includes a plurality of in-phase and quadrature phase receive processing blocks operable at first and second frequency bands and further includes a plurality of filtering and amplification blocks disposed within a corresponding ingoing signal path, a plurality of received signal strength indicator (RSSI) blocks coupled to receive an ingoing analog signal from a corresponding plurality of nodes disposed throughout the ingoing signal path, each of the plurality of RSSI blocks producing a signal strength indication, and wherein a baseband processor is operable to receive a selected signal strength indication and to produce at least one gain setting to at least one amplification block within the in-phase or quadrature phase receive processing blocks. In operation, the baseband processor receives a signal strength indication from each RSSI block to determine a total amount of gain and appropriate gain distribution within the receive signal path.
