Abstract: Disclosed are an apparatus and a method for normally receiving data by accurately estimating and compensating for a frequency offset for a wireless frequency channel through which data are transmitted in a communication system under wireless frequency environment. In the present invention, data transmitted through the wireless frequency channel are received, the frequency offset in the wireless frequency channel from the receive data is estimated based on an interpolation scheme using the periodogram, and the frequency offset is compensated to receive the data by frequency-synchronizing with the wireless frequency channel.

Abstract: An apparatus for allocating resources in a communication system includes a reception unit configured to receive information on a terminal from the terminal when the terminal initially accesses the apparatus in order to receive communication service, a determination unit configured to check information on a bandwidth for providing the communication service to the terminal, the information on the terminal, and information on a satellite and determine the size of a resource block group to be allocated to the terminal by taking the information on the bandwidth, the information on the terminal, and information on the satellite into consideration, and an allocation unit configured to allocate resource blocks corresponding to the size of the resource block group to the terminal in order to transmit and receive data packets to and from the terminal.
