  Abstract

This paper describes waveform of Space-Time Dynamic Spectrum Access (ST-DSA) scheme whose main idea is to detect and utilize frequency voids across the space and time domain. Implemented on a SDR platform, ST-DSA waveform interfaces with active phased-array antenna used for exploiting space domain, and it controls main functions including T/Rx and DSA. Consisting of Physical Layer, Link/MAC Layer, and Application Layer, ST-DSA waveform is verified by implementing MATLAB based simulator. It is also verified by deploying outdoor test-bed, on which several tests are performed to ensure real environmental operability of the main functions of the waveform.
