Patent ID: 8509355

Claim:
A method comprising: receiving a radio frequency (RF) baseband signal in a radio receiver; splitting the received RF baseband signal into first and second identical versions of the received RF baseband signal; processing the first version of the received RF baseband signal in a limited phase-shift keying (PSK) correlation path that includes limiting the first version of the received RF baseband signal to generate a limited version of the received RF baseband signal having limited data, operating a correlator on the limited version of the received RF baseband signal to simultaneously determine coarse frequency and timing estimations for the received RF baseband signal; and processing the second version of the received RF baseband signal in an automatic gain control path that includes performing automatic gain control on the second, non-limited version of the received RF baseband signal substantially simultaneously with the coarse frequency and timing estimations determined by the correlator in the limited phase-shift keying (PSK) correlation path.
