Initial Results of Carrier Frequency Offset Estimation for Pseudo Random Noise Code in BPSK Modulation

This paper presents the process of finding carrier frequency offset (CFO) caused by doppler and local oscillator (LO) differences in Software Defined Radio on Pseudo Random Noise (PRN) code modeled with Binary Phase Shift Keying (BPSK). The CFO search process yields accurate results at 2 times the initial baseband frequency transmitted plus the LO difference.
