Abstract：The principle of synchronization in FD/SSMA (Frequency Diversity/Spread Spectrum Multiple Access) system with DFT (Discrete Fourier Transform) implementation is studied. It is shown that both byte-timing synchronization (i.e. the time-window of DFT transform) and the transmitter carrier synchronization are needed in this FD/SSMA system. The capturing, locking and tracing of timing-synchronization, the carrier s synchronization about its frequency and phase will be finished in order by the recognizing signals of timing-synchronization and three error signals, of which the timing-error signal, the frequency and phase error signals
of the system’ carrier are included, where their implementation may be carried out easier due to the DSP (Digital Signal Processing) techniques to be applied.
