Abstract
The present disclosure relates to a communication method and system for converging a 5G communication system for supporting higher data rates beyond a 4G system with an IoT technology. The present disclosure may be applied to intelligent services based on the 5G communication technology and the IoT-related technology, such as smart home, smart building, smart city, smart car, connected car, health care, digital education, smart retail, security and safety services. The present disclosure can reduces a peak-to-average power ration (PAPR) by performing time domain cyclic filtering. Further, a data rate or coverage can be improved by selectively transmitting transmission waveforms through cyclic prefix (CP)-orthogonal frequency division multiplexing (OFDM) or discrete Fourier transform-spread-OFDM (DFT-s-OFDM).
