Patent ID: 8442020

Claim:
A method of generating a position, comprising: receiving from a transmitter a binary offset carrier (BOC) signal, the BOC signal including an upper sideband signal and a lower sideband signal; down converting the received BOC signal to a baseband signal by using filters, the filters lacking linear phase response across a pass-band; correlating the BOC signal with a first replica signal and a second replica signal, the first replica signal and the second replica signal being square wave signals, the first replica signal being a BOCSINE replica signal, the second replica signal being a BOCCOS replica signal, the BOCSINE replica signal being ninety degrees out-of-phase relative to the BOCCOS replica signal, wherein correlating provides a plurality of correlator outputs, the plurality of correlator outputs including a BOCSINE correlator output and a BOCCOS correlator output, the BOCSINE correlator output being ninety degrees out-of-phase relative to the BOCCOS correlator output; and processing the converted baseband signal to remove errors due to phase distortion of the BOC signal, wherein the processing includes applying a complex rotation to a combination of the BOCSINE correlator output and the BOCCOS correlator output, the complex rotation correcting for a non-linear component of a phase response of a processing channel, the processing channel having a non-linear phase, said processing being carried out at a post detection integration (PDI) rate.
