Abstract
Disclosed is an apparatus, method and computer program which frequency shifts a received signal by a first frequency value and low-pass filters the frequency shifted received signal at a first cutoff frequency to filter out a plurality of adjacent carrier frequencies. Parallel baseband processing is then performed on two or more adjacent carrier frequencies among the plurality of adjacent carrier frequencies based upon an adjacent carrier power criterion. In certain examples, the parallel baseband processing is adapted for detecting a frequency correction burst in two or more adjacent Global System for Mobile Communications carrier frequencies or an Enhanced Data Rates for Global System for Mobile Communications Evolution carrier frequencies.
