Abstract
A signal transmission apparatus in a Double Orthogonal Frequency Division Multiplexing (DOFDM)/Double Orthogonal Frequency Division Multiple Access (DOFMA) communication system generates a first signal by performing row-wised Orthogonal Frequency Division Multiplexing (OFDM) on M sub-samples for each of N sub-carriers, generates a second signal by performing column-wised OFDM on the first signal generated for each of the N sub-carriers, and transmits the second signal to a signal reception apparatus. Here, N denotes a number of sub-carriers used in the DOFDM/DOFDMA communication system, and M denotes an integer greater than or equal to 1.
