METHOD FOR TRANSMITTING/RECEIVING SIGNAL HAVING SPREAD TRAINING SYMBOL IN MOBILE COMMUNICATION SYSTEM

摘要

A method for transmitting/receiving signals in a mobile communication system, a pilot configuration of a mobile communication system capable of transmitting much more data using a conventional pilot signal, a channel estimation method, and a receiving method are disclosed. A method for transmitting a signal equipped with a training symbol in a mobile communication system which includes a transmission end capable of transmitting an output signal equipped with a training symbol for channel estimation of a reception end, includes the steps of: a) adding training symbols having the same amplitude to data symbols transmitted via subcarriers, and calculating the output signal transmitted via the subcarriers; and b) transmitting the calculated output signal via the subcarriers.
