Evaluación de calidad de servicio en telemedicina independiente de la infraestructura de red de datos

Abstract

This work evaluates the QoS parameters necessary to guarantee the reliable transmission of biomedi- cal signals in telemedicine environments, considering different network infrastructure scenarios. A compu- tational simulation was developed in Matlab, where the transmission of medical signals such as ECG, EEG, diagnostic images (CT, X-rays) and video se- quences was modeled over a noisy AWGN channel, using QPSK modulation and without applying chan- nel coding techniques, with the objective of evaluating the performance under realistic conditions and with limited resources. As part of the analysis, various available communication technologies were compared, as a technically viable option for environments where access to more advanced technologies is limited. The results demonstrated that it is possible to achieve ac- ceptable diagnostic quality if the SNR exceeds 9.5 dB, with a BER lower than 10−3. This study contributes to establishing technical guidelines for the efficient implementation of digital health services, even in regions with restricted network infrastructure.
