Abstract
Systems and methods for correcting frequency error in a received signal include: receiving a satellite signal, the satellite signal having a bandwidth and a center frequency; determining the profile of the satellite signal; computing the center frequency of the satellite signal based on the profile of the received signal; and generating a reference signal at the computed center frequency. The systems and methods may further include computing a center frequency of each of a plurality of satellite signals based on the computed center frequency. Determining the profile may include sweeping a tuner above and below a given reference frequency; measuring the received signal strength during the sweeping operation; and determining the profile based on the received signal strength.
