Combined source-channel transform for image transmission over wireless channel
Mike Sabelkin, François Gagnon · 2011
The proposed communication system is based on a combined source-channel transform. Given particular scenarios of still image transmission over a wireless LOS channel, the proposed system demonstrates superior performance compared to a JPEG2000 + WirelessMAN OFDM system in restored image quality parameters over a wide range of wireless channel parameters. The proposed system provides progressive lossless image transmission under influence of moderate fading without any kind of channel coding. The proposed system employs a fast analysis/synthesis algorithm, which does not use any multiplications, and it uses three times less real additions than the one of JPEG2000 + WirelessMAN OFDM.
