Abstract

See full text

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). A method and apparatus for channel estimation and equalization in a cellular environment based on quadrature amplitude modulation-filter bank multicarrier (QAM-FBMC) transmission is provided. The signal transmission method for a transmitter includes sending channel measurement information to a receiver, receiving channel related information from the receiver, selecting a first filter and a second filter to be used for signal transmission according to the received channel related information, mapping, when no performance difference is present between the first filter and the second filter, reference symbols evenly to subcarriers associated with the first filter and subcarriers associated with the second filter, mapping, when a performance difference is present between the first filter and the second filter, reference symbols preferentially to subcarriers associated with the transmitting filter with higher performance, and sending a transmit signal having the mapped reference symbols.
