Performance analysis of JPEG2000 transmission through low SNR MC-CDMA channel
Thiyagu Kathiyaiah, Tick Hui Oh · 2009
The demand for high data rate transmission is ever increasing everyday. Multi-carrier code division multiple access (MC-CDMA) system is considered as the forerunner and advancement in the mobile communication system. In this paper, two types of JPEG2000 lossily-compressed test images are transmitted through an MC-CDMA channel in low SNR (as low as 4dB) environment and their quality are evaluated objectively by using peak signal-to-noise ratio (PSNR) and root mean square error (RMSE). The test images are all compressed in the ratios of 10∶1 up to 70∶1 and the system involves multi-user image transmission in near real-time low SNR (±5dB). It is found that JPEG2000 image compression technique that applies wavelet transform performed rather well in the low SNR multipath fading channel and it looks quite promising for future applications.
