In this paper we perform a system-level analysis of a wireless biosignal telemetry system. We perform an analysis of each major system component (e.g., analog front end, analog-to-digital converter, digital signal processor, and wireless link), in which we consider physical, algorithmic, and design limitations. Since there are a wide range applications for wireless biosignal telemetry systems, each with their own unique set of requirements for key parameters (e.g., channel count, power dissipation, noise level, number of bits, etc.), our analysis is equally broad. The net result is a set of plots, in which the power dissipation for each component and as the system as a whole, are plotted as a function of the number of channels for different architectural strategies. These results are also compared to existing implementations of complete wireless biosignal telemetry systems.
在本文中，我们对无线生物信号遥测系统进行了系统级分析。我们对每个主要系统组件（例如，模拟前端、模数转换器、数字信号处理器和无线链路）进行了分析，其中我们考虑了物理、算法和设计限制。由于无线生物信号遥测系统有广泛的应用，每个应用对关键参数（例如，通道数、功耗、噪声水平、位数等）都有其独特的要求集，我们的分析同样广泛。最终结果是一组图表，其中每个组件以及整个系统的功耗作为不同架构策略下通道数的函数被绘制出来。这些结果还与完整无线生物信号遥测系统的现有实现进行了比较。
