Abstract  Abstract

PURPOSE: A method and device for transmitting/generating an uplink signal of a communication system are provided to change a cyclic shift according to time, thereby randomizing interferences between users and cells. CONSTITUTION: An RF receiving unit(210) receives K user signals transmitted from K terminals and converts the K user signals into baseband signals. An analog to digital converter(220) converts a baseband signal into a digital receiving signal. A CP eliminating unit(230) eliminates a CP(Cyclic Prefix) from the digital receiving signal. A serial/parallel converting unit(240) converts the signal from which the CP is eliminated into a parallel receiving signal. An FFT(250) converts the parallel receiving signal into a frequency domain receiving signal by fast Fourier transform.
