Abstract :
This paper presents a burst modulation/demodulation method for narrowband wireless communication systems, whose traffic is especially dominated by short packet bursts. In order to improve transmission efficiency and burst synchronization performance, the proposed method provides a preamble-less frame structure with minimum number of training symbols. This paper also presents the experimentally measured performance of hardware prototypes of the proposed modulator and demodulator. The basic operation and practical performance are confirmed through testbed studies.
