Patent ID: 7532687

Claim:
A method for processing a signal in a receiver in accordance with Ultra Wideband (UWB) protocol, the method comprising: splitting the signal into a pulse component and a noise component; acquiring the signal during a first preamble portion of a data frame associated with the UWB protocol and, during the acquiring, performing a first Automatic Gain Control (AGC) operation associated with a noise component of the signal using AGC circuitry; and performing a second AGC operation associated with a pulse component of the signal after acquiring the signal during a second preamble portion of the data frame associated with the UWB protocol using the AGC circuitry, the first preamble portion being different from the second preamble portions, wherein the performing the first AGC operation associated with the noise component of the signal includes adjusting the noise component of the signal to an approximate value proportional to a received power level associated with the signal and an approximate Root Mean Square (RMS) value.
