Abstract
A method for transmitting a signal according to the present invention comprises spreading a control channel data through a PN code and generating a diffused control channel data; time division multiplexing the diffused control channel data and a service channel data and generating a multiplexed signal; and inverse Fourier transforming the multiplexed signal and generating an inverse Fourier transformed signal. Accordingly, in multi-hop communication, frequency efficiency is improved by not using different RF frequencies between a control channel and service channel, and applying a control channel and service channel through the TDM (Time Division Multiplexing) method, and the channel efficiency is improved by WAVE channel switching.
