Abstract:
This paper proposes a joint source-channel coding technology to transmit periodic vital information such as an electrocardiogram (ECG). It shows the iterative decoding method using a correlation value which can be obtained from ECG periodicity as Side-Information. The improvement is shown when bit strings are transmitted with different encoding rates. Because the proposed method has an error correcting system and makes a code processing decrease, some miniaturization and energy-saving can be expected of the equipment. Finally, the effectiveness of the proposed method is shown by comparisons with Differential Pulse Code Modulation, which is a typical compression method of ECG, and with the no coding method.

Basic Continuous Time Signals
The unit step function, denoted u(t), is zero for negative time values and one for positive time values, exhibiting a discontinuity at t=0. This function often represents abrupt changes, such as the step voltage introduced when turning a car's...
