- In this paper, we propose a new residual carrier frequency and timing offset tracking scheme for a SC-FDE(Single Carrier - Frequency Domain Equalizer) with frequency-domain pilots. The SC-FDE is a field that gathers more and more interest as a modulation scheme for the broadband wireless communications. For simple channel equalization, SC-FDE systems perform equalization in frequency-domain instead of time-domain using FFT, IFFT and CP(Cyclic Prefix). We analize the effect of frequnecy and timing offset in a frequency-domain and propose new method of frequency and timing synchronization. Also, we describe a method to assign frequency-domain pilots and tracking algorithms for residual carrier frequency and timing offset using these pilots. Moreover, we verify the algorithm with a numerical analysis and computer simulation. © 2003 IEEE.
