Frequency synchronisation using SS technique

Timing synchronisation is achieved by time (T)-division spread spectrum (SS) code acquisition. Frequency (F)-domain SS code acquisition method is proposed for the recently proposed F-division SS system (FD/S3), which uses T-domain correlation and permits frequency offset. Frequency dual of this method gives a new T-domain code acquisition with F-domain correlation, which is more resistant to frequency offset than the conventional one with T-domain correlation.
