Patent Images
1. A wireless network receiver, comprising:
- a preamble detection module that uses preamble bits in a data frame for signal processing functions; and
wherein the preamble detection module adjusts the number of preamble bits that are used in response to the power of a received signal;
wherein the preamble detection module performs a plurality of signal processing functions using the preamble bits;
wherein the number of preamble bits that are used by each signal processing function is variable based on the power of the received signal; and
wherein at least one signal processing function uses a predetermined maximum number of preamble bits where the predetermined maximum number is based on limiting processor instruction cycles.

7. 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; and an automatic amplifier gain control module that measures the power of the received signal and sends power information to the preamble detection module; wherein 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 wherein the preamble detection module uses a first number of preamble bits for signal processing when the required number of gain adjustment steps is zero, and where the detection module uses a second number of preamble bits for signal processing when the required number of gain adjustment steps is one. - View Dependent Claims (8)

16. A method, comprising:
-
receiving, by a wireless network receiver, a signal; using, by a preamble detector module in the wireless network receiver, preamble bits in the signal for signal processing; adapting, by the preamble detector module, the number of preamble bits being used, in response to the power of the signal; determining, by an amplifier module, the number of amplifier gain adjustment steps needed, based on the power of the signal; sending, by the amplifier module, information indicating the number of amplifier gain adjustment steps needed to the preamble detector module; and the step of adapting further comprising; using, by the preamble detector module, a first number of preamble bits for signal processing when the number of amplifier gain adjustment steps is zero; and using, by the preamble detector module, a second number of preamble bits for signal processing when the number of amplifier gain adjustment steps is one. - View Dependent Claims (17)
