Classifier for IEEE 802.11g receiver

摘要

Classifier for IEEE (Institute of Electrical & Electronics Engineers) 802.11g receiver. 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.
