INTEGRATED WIRELESS-BASED MEDICAL INFORMATION PROCESSING: SYSTEM ANALYSIS AND SIMULATION

摘要

Accuracy of information processing and transmission is of essential importance in designing integrated systems of medical diagnosis and communications. When system resources are limited, such as transmission bandwidths, appropriate utility of available resources to minimize information errors becomes imperative. In this paper impact of communication channel resource limitations on medical information processing is studied. Fundamental relationships between information exchange accuracy and available resources, and tradeoff among communication system variables are established under typical communication settings with DCT transformation, data compression, quantization, stochastic wireless channels and IDCT transformation. Lung sound data acquisition and diagnosis are employed to illustrate the main findings.
