Title
A synchronization scheme for multi-carrier CDMA systems
Abstract
A new time-domain synchronization scheme for multi-carrier CDMA systems is developed, which does not require the DFT or FFT of the whole OFDM block. This scheme is particularly proposed for being used with the time-domain data detection techniques which do not need the whole DFT analysis of the input signal [1][2]. Timing detection is performed using the correlation property of the guard interval in the time domain. The carrier frequency synchronization is performed in two steps: tracking to the nearest subcarrier frequency followed by correction of the remaining frequency offset, which is a multiple of the subcarrier frequency interval. The guard interval-based frequency offset detection method is employed for the first step [3]. A synchronization block containing null symbols on a small number of subcarriers is proposed for the second step, which enables efficient implementation of frequency offset detection using the decimation-in-frequency technique.
