This paper presents a new automatic-frequency control (AFC) configuration capable of removing wide range frequency offsets (up to about ±0.625 fs, where is is signal symbol rate). The new configuration consists of an AFC that removes frequency offsets between ±0.125 fs and another AFC that detects the frequency offset range coarsely between ±0.625 fs. This paper describes the principle of the new AFC configuration. The proposed AFC configuration employs four correlators to enhance the acquisition range. It also adopts the reverse modulation scheme to decrease the acquisition time. The performance of the new AFC configuration is confirmed via computer simulations. It is shown that the proposed configuration can accommodate wide range frequency offsets as well as reduce the. acquisition time.
