METHOD FOR SIGNAL TRANSMITTING AND APPARATUS FOR THE SAME, METHOD FOR SIGNAL RECEIVING AND APPARATUS FOR THE SAME

摘要

A signal transferring method and a signal transmit-receive device for improving data transfer rate based on SNR(Signal To Noise) gain are provided to reduce a cost and convert the device into signal transmission system by using signal transmission network. A forward error correction unit(100) outputs and encodes input signal. Data interleaved in a first interleaver(110) are input to the trellis code modulation section(120). A linear precoding part(130) disperses inputted symbol data into several output-symbol data. A second interleaving(140) again does symbol data outputted in the linear precoding unit. A multiple input multiple output encoder(150) encodes a plurality of transmission antennae data interleaved in the second interleaving. A frame formation part(160) forms precoded signal in an OFDM(Orthogonal Frequency Division Multiplex) by inserting pilot signal.
