Patent ID: 7864891

Claim:
A method for acquiring a frequency correction burst using a radio communication device, the method comprising: receiving RF signals, by an RF circuit, to provide received RF signals; processing, by digital processing circuitry, the received RF signals, the digital processing circuitry including first and second digital processing circuits; and controlling, by a time management unit, the RF circuit to activate the RF circuit to provide an acquisition time window during which the RF circuit receives RF signals intended to be processed by the digital processing circuitry, wherein the acquisition time window is discontinuous and includes N sub-acquisition windows during which the RF circuit is activated and during which the first digital processing circuit is activated to detect the frequency correction burst while the second digital processing circuit is deactivated, the sub-acquisition windows of the acquisition time window being separated from one another by Nâˆ’1 non-acquisition time slots during which the RF circuit is deactivated, wherein Nâ‰§2.
