Title: FILTERING-BASED SIGNAL TRANSMISSION AND RECEIVING METHODS AND CORRESPONDING TRANSMITTER AND RECEIVER
Abstract:
The present disclosure relates to a communication method and system for converging a 5th-Generation (5G) communication system for supporting higher data rates beyond a 4th-Generation (4G) system with a technology for Internet of Things (IoT). 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. A filtering-based signal transmission method is provided. The method includes by a transmitter performing carrier modulation on each signal from at least one sub-band, and adding a cyclic prefix and a cyclic postfix thereto, respectively, performing time-domain filtering on the signal, added with the cyclic prefix and the cyclic postfix, from the respective sub-band, and transmitting the filtered signal from the at least one sub-band. The present disclosure further provides a filtering-based signal receiving method, comprising performing, by a receiver, time-domain matched filtering, corresponding to at least one sub-band, on each received signal, removing, by the receiver, a cyclic prefix and a cyclic postfix from the filtered signal from the at least one sub-band, and performing carrier demodulation, respectively, and detecting and estimating, by the receiver, the demodulated signal from the at least one sub-band.
