Patent ID: 8755849

Claim:
A method for signal processing, the method comprising: managing power consumption in a wireless device by configuring one or more of a plurality of transmitters of said wireless device, wherein, at a given time, said wireless device is configured into one of a plurality of modes, said modes comprising: a first mode in which only one of said plurality of transmitters of said wireless device is enabled, where said only one of said plurality of transmitters that is enabled is determined based on a directivity of a received signal and a signal strength of said received signal measured utilizing fast fourier transformation (FFT) analysis in said wireless device, said received signal comprising a combination of received signals from each of said plurality of transmitters; a second mode in which a variable number of said plurality of transmitters are enabled, and said variable number is automatically varied based on said directivity of said received signal and said signal strength of said received signal measured utilizing said FFT analysis in said wireless device; and a third mode in which all of said plurality of transmitters are enabled, regardless of said directivity of said received signal and said signal strength of said received signal, wherein a phase shift is configured using a measurement of said received signal and a table stored in a memory of said wireless device that includes phase shift coefficients for each of said plurality of transmitters, said measurement made utilizing said FFT analysis in said wireless device.
