Communication method for frequency hopping ofdm based cellular system

The present invention is frequency hopping (FH) orthogonal frequency division multiplexing (OFDM) as a method to distinguish between the base station in a communication system, and perform the initial synchronization, the system includes a pilot pattern of a predetermined number, and different for the pilot transmission of the pilot and generating a pilot pattern group of a predetermined number of used subcarriers, and to each other corresponding different frequency hopping sequence combinations for each of the pilot pattern in the pilot pattern group, to the plurality of terminals communicating in a service area of ​​the plurality of base stations so that the base station can identify the base station allocates to the different pilot pattern and a frequency hopping sequence and the corresponding combination. UE identify the pilot pattern group, and wherein the detected pilot samples corresponding by receiving a plurality of symbols comprising each pilot samples from the base station detects the pilot samples are cylindrical subcarriers for each of the symbols on the pilot subcarriers by detecting the pattern of the frequency hopping sequence estimates a combination corresponding to the pilot pattern to receive data from the base station.
