Data transmission oriented on the object, communication media, application, and state of communication systems: Tactical communication system application.

摘要

A proposed communication system architecture is denoted TOMAS, which stands for data Transmission oriented on the Object, communication Media, Application, and state of communication Systems. Given particular tactical communication system scenarios of image transmission over a wireless LOS (Line-of-Sight) channel, a wireless TOMAS system demonstrates superior performance compared to the conventional system, which is a combination of JPEG2000 image compression and OFDM transmission, in restored image quality parameters over a wide range of wireless channel parameters. The wireless TOMAS system provides progressive lossless image transmission under the influence of moderate fading without any kind of channel coding and estimation. The TOMAS system employs a fast proprietary patent pending algorithm Sabelkin (2011), which does not employ any multiplications, and it uses three times less real additions than the algorithm of JPEG2000+OFDM. The TOMAS system exploits a specialized wavelet transform combined for image coding and channel modulation.;Keywords: Tactical Communication System (TCS), Line-of-Sight (LOS), Wavelets, Wavelet Packets, Joint Photographic Experts Group (JPEG), JPEG2000, Quality of Service (QoS), multipath channel, Software Defined Radio (SDR), Error Sensitivity Descriptor (ESD), Orthogonal Frequency Division Multiplexing (OFDM), Wavelet Packet Multiplexing (WPM).
