Abstract
Provided is an apparatus for signal transmission in a Fast Frequency Hopping-Orthogonal Frequency Division Multiplexing (FFH-OFDM) communication system which divides all of the available frequency bands into a plurality of sub-carrier bands and includes a plurality of sub-channels each including at least one sub-carrier band. The apparatus includes: a Fast Frequency Hopping (FFH) unit for allocating input data to a number of selected sub-carriers from among the plurality of sub-carriers and for performing fast frequency hopping in accordance with a fast frequency hopping pattern to generate FFH signals, wherein one or more pieces of data comprise the input data and each of the one or more pieces of data is allocated to one of the selected sub-carriers; a Fast Fourier Transform (FFT) unit for performing FFT on FFH signals; a controller for inserting null data into remaining sub-carriers, the remaining sub-carriers comprising sub-carriers other than the selected sub-carriers; a first Inverse Fast Fourier Transform (IFFT) unit for performing IFFT on both the selected sub-carriers comprising the input data and the remaining sub-carriers comprising the inserted null data to generate fir…
