Patent ID: 7437136

Claim:
A method for recording data from a wireless communication transmission with a receiver in a device that includes a digital processor, the method comprising: disabling at least a portion of non-essential electronics including the digital processor when the receiver is in a receive mode; starting a capture sequence for the receiver in the receive mode; receiving the wireless communication transmission during the receive mode; identifying an received in-phase (I) signal and a received quadrature-phase (Q) signal from the received wireless communication transmission during the receive mode, wherein the received in-phase (I) signal and the received quadrature phase (Q) signal correspond to a complex base-band signal; digitizing the complex base-band signal from a captured transmission during the receive mode, wherein the digitized complex base-band signal comprises a digitized in-phase (I) signal and a digitized quadrature phase (Q) signal; storing the digitized complex base-band signal in a buffer without further processing; exiting the receive mode after the capture sequence is completed and after each digitized complex base-band signal is stored; re-enabling the previously disabled at least the portion of non-essential electronics including the digital processor after the receive mode is exited; and reassembling digital data from the wireless communication transmission using the previously stored digitized complex base-band signals with the digital processor when re-enabled after the receive mode is exited such that the effects of noise in the digitized complex base-band signal are minimized by disabling the at least the portion of non-essential electronics including the digital processor while the digitized complex base-band signal is received.
