Abstract: Proposed is a method for transmitting and receiving data based on distributed beamforming performed by a distributed beamforming-based data transmission and reception system including ground operation equipment and a plurality of distributed nodes. The method may include determining a master node among the plurality of nodes through the ground operation equipment, and forming a data transmission and reception channel based on a signal reception level between the master node and a slave node. The method may also include transmitting and receiving data between the master node and the slave node through the formed data transmission and reception channel.

Abstract: A method of processing a signal in a compressive sensing receiver, includes: obtaining a first signal received via an antenna; generating a first baseband signal by mixing the first signal with a second signal generated by a local oscillator based on a pseudo random binary sequence (PRBS); removing a spurious from the first baseband signal based on a pre-stored estimation value obtained by estimating the spurious generated by the local oscillator in advance; and detecting a spectral slice including the first signal based on the first baseband signal from which the spurious is removed and a measurement matrix.
