Abstract

Disclosed are a method and apparatus for channel estimation and equalization. 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.

Description

technical field [0001] The present disclosure relates to channel estimation and equalization in a cellular environment based on quadrature amplitude modulation (QAM)-filter bank multi-carrier (FBMC) transmission technology. More specifically, the present disclosure relates to a method and apparatus by which reference symbols (RS) are mapped to subcarriers through two different filters, and channel estimation is performed by using the RS for each filter and using The estimated channel information is used to perform equalization. Background technique [0002] To meet the increased demand for wireless data traffic since the deployment of 4G communication systems, efforts have been made to develop improved 5G or pre-5G (pre-5G) communication systems. Therefore, the 5G or quasi-5G communication system is also called "a network beyond 4G" or a "post-LTE system". [0003] The 5G communication system is considered to be implemented in a higher frequency (millimeter wave) band, suc...
