본 논문에서는 심전도 등 주기적인 생체 정보를 전송하기 위한 공동 소스-채널 코딩 기술을 제안한다. 측정된 생체정보를 바탕으로 맞춤형 진료가 자동으로 제공되는 유비쿼터스 진료 공간이 절실히 요구되고 있다. 이러한 치료를 실현하고 환자에 대한 제약을 줄이기 위해서는 센서 장치에서 데이터 수집기로 중요한 정보를 무선으로 전송하는 것이 필수적입니다. 하지만 중요한 정보는 무선 채널을 통해 정확하게 전달되어야 합니다. 또한 센서 장치는 배터리 전원으로 인해 제한됩니다. 따라서 인코딩 시 잡음에 대한 강인성, 채널 효율성 및 낮은 전력 소모를 제공하는 코딩 기술이 필수적입니다. 본 논문에서는 시간 영역에서 주기적인 필수 정보의 상관관계를 이용한 코딩 방법을 제시하고, 이를 최대 사후확률 알고리즘에서 부가정보로 활용하는 복호화 방식을 제공한다. 우리의 결과는 제안된 방법이 차동 펄스 코드 변조 및 코딩되지 않은 경우와 비교하여 디코딩 후 평균 제곱 오차 측면에서 더 나은 성능을 제공한다는 것을 보여줍니다.

Abstract: This paper proposes a joint source-channel coding technology to transmit periodic vital information such as an electrocardiogram. There is an urgent need for a ubiquitous medical treatment space in which personalized medical treatment is automatically provided based on measured vital information. To realize such treatment and reduce the constraints on the patient, wireless transmission of vital information from a sensor device to a data aggregator is essential. However, the vital information has to be correctly conveyed through wireless channels. In addition, sensor devices are constrained by their battery power. Thus, a coding technique that provides robustness to noise, channel efficiency and low power consumption at encoding is essential. This paper presents a coding method that uses correlation of periodic vital information in the time domain, and provides a decoding scheme that uses the correlation as side information in a maximum a posteriori probability algorithm. Our results show that the proposed method provides better performance in terms of mean squared error after decoding in comparison to differential pulse-code modulation, and the uncoded case.
