US 9,960,887 B2 · Method and apparatus of signal transmission and reception in a filter bank multiple carrier system

Abstract

The present disclosure relates to a pre-5th-Generation (5G) or 5G communication system to be provided for supporting higher data rates Beyond 4th-Generation (4G) communication system such as Long Term Evolution (LTE). Provided is a method of transmitting signals in an FBMC/OQAM system. Data symbols transmitted in category-2 data symbols or category-3 data symbols are determined according to interference from all of adjacent OQAM data symbols and an intrinsic interference coefficient of category-2 data symbols interference experienced by category-3 data symbols in a user data block, so that transmission symbols in the category-3 data symbols composed of transmitted data symbols and interference include target data symbols of the category-3 data symbols and target data symbols of the category-2 data symbols. A transmitting device transmits the data symbols of the category-3 data symbols and data symbols transmitted in category-2 data symbols together with other data symbols in the user data block.
