Abstract :
In this paper, we examine synchronization of large carrier frequency offsets in low signal-to-noise ratio (SNR) environments. We show that a misadjustment of the receive filter in terms of its center frequency involves a significant SNR degradation that cannot be compensated for after receive filtering. In order to avoid degradations in the bit error rate of the system, we propose an iterative approach to circumvent this problem.
