OFDM TRANSMISSION/RECEPTION DEVICE FOR TRANSMITTING AND RECEIVING OFDM SYMBOLS HAVING A VARIABLE DATA TRANSMISSION RATE AND METHOD THEREOF

摘要

An OFDM transmission apparatus is provided which transmits OFDM symbols to at least one reception apparatus. The apparatus includes an OFDM transmission processing unit which generates a plurality of OFDM symbols, a pilot insertion unit which inserts a pilot into each OFDM symbol, and a control unit which controls the pilot insertion unit to insert the pilot according to a pilot insertion pattern which is determined to correspond to a communication environment from among a plurality of pilot insertion patterns. Therefore, a data transmission rate adopted to the communication environment can be obtained.
