Abstract
Official abstract text for this publication.
A wireless network receiver includes a detection module that uses preamble data in a data frame for signal processing functions and the detection module is configured to adjust the number of preamble data bits that are used based on the power of a received signal.
First claim
Opening claim text (preview).
What is claimed is: 1. A wireless network receiver, comprising: a preamble detection module that uses preamble bits in a data frame for signal processing functions; wherein the preamble detection module adjusts the number of preamble bits that are used in response to the power of a received signal; an automatic amplifier gain control module that measures the power of the received signal and sends power information to the preamble detection module; where the power information specifies a number of amplifier gain adjustment steps that will be required in response to the power of the received signal; and where the preamble detection module uses a first number of preamble bits for signal processing when the required number of gain adjustment steps is less than a predetermined threshold, and where the preamble detection module uses a second number of preamble bits for signal processing when the required number of gain adjustment steps is greater than the predetermined threshold.
