摘要：Therefore, the main objective of this study is to develop a new simulation application for medical data compression and transmission based Wi-Fi IEEE 802.11 with high robust in term of image quality endurance to noise caused by transmission signal. The development of two main modules, namely, Wi-Fi transmission and medical data compression modules is required to achieve this objective. The focus of the study is to find a new method of medical data compression that has good ability to transmit the medical data even though any noise occurs during data transmission. The Wi-Fi transmission module was developed based on IEEE 802.11b protocol in 1 Mbsp data size transmission. The medical data compression modules were developed based on shared dictionary data between sender and receiver part. The shared dictionary was computed by Independent component analysis (ICA) using each type of medical data. In this study, tree type of data was used to generate shared dictionary: natural image, ultrasound image and fundus image. The performance evaluation includes two parts for the measurement of the error during simulation. First, the performance results related to the transmitted and received data similarity that represented by an error bit. The second performance results are regarded as the similarity between original image before and after transmitted that computed using a peak signal noise ratio (PSNR). The developed compression shows promising results with a capability of restoring image with PSNR 30 dB using medical image. In conclusion, this research has achieved its stated goal of developing a simulation application for medical data compression and transmission based Wi-Fi IEEE 802.11b.
