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). The present invention discloses a transmitting and receiving method capable of estimating an accurate time and a frequency synchronization using a sequence in a filter bank multiple transmission system.
Claims11
A method in a communication system, the method comprising:
- generating a first pilot sequence including synchronization information;
- selecting a random block among a plurality of blocks in which the first pilot sequence is included;
- determining an auxiliary symbol of an auxiliary sequence based on an average power of the selected random block;
- generating the auxiliary sequence related to a correlation attribute of the first pilot sequence;
- mapping the first pilot sequence and the auxiliary sequence to a plurality of subcarriers in at least one data symbol;
- and
- transmitting data on the at least one data symbol to which the first pilot sequence and the auxiliary sequence are mapped,
- wherein the selected random block is a block of which a transmission power value of a target pilot sequence among the plurality of blocks is largest.
