摘要：The present invention provides a method for transmitting and receivingorthogonal frequency division multiplexing (OFDM) signals. The transmission methodincludes the steps of: (a) coding the OFDM signals; (b) forming a block of N coded dataand dividing the block into L M-sized small blocks, where N, M and L indicate integers of1 or more, and L = N/M; (c) M-point inverse fast Fourier transforming the L small blocks;(d) combining L M-point inverse fast Fourier transformed blocks, and generating an N-sized inversely-transformed block; (e) attaching a cyclic prefix to the N-sized inversely-transformed block; and, (f) transforming the blocks having the attached cyclic prefix, intoan analog signal and transmitting the transformed analog signal. Accordingly, comparedto a typical OFDM method, the PAR of a signal is significantly reduced, and compared to atypical single carrier method, the structure of an equalizer is simplified.
