Abstract

A method for transmitting orthogonal frequency division multiplexing (OFDM) signals including coding the OFDM signals; forming a block of N coded data and dividing the block into L M-sized small blocks; M-point inverse fast Fourier transforming the L small blocks; combining the transformed blocks to generate an N-sized inversely-transformed block; attaching a cyclic prefix to the N-sized block; and transforming the blocks into an analog signal; and transmitting the analog signal. A method of receiving OFDM signals including digitally converting received OFDM signals and obtaining a samples from the transformed signals; detecting the starting point of an N-sized signal sample block from the samples; dividing the signal sample block into L M-sized small blocks M-point fast Fourier transforming the L small blocks; combining the transformed small blocks to generate an N-sized transform block; detecting data from the generated block, and decoding the detected data. N, M and L are integers of 1 or more and L=N/M.
