We are interested in a communication system that operates under stringent power constraints, but is flexible with bandwidth constraints. Our approach is to consider some of the key elements in a transceiver and optimize them for low power consumption, as opposed to optimizing them to minimize, say, average probability of error. An obvious consequence of this is that high complexity components of the system, such as matched filters, forward error correction that employs iterative decoders, coherent demodulators, and bandwidth-efficient modulation formats, are not feasible for this research. Rather, our system is designed using $M$ -ary FSK with non-coherent detection, optimized two-pole bandpass filters (BPF), and Reed-Solomon (RS) codes with hard-decision decoding. Among other things, we show that by properly optimizing the key parameters of the BPFs and RS codes, we can design the system to be significantly less complex than an optimal one, and only lose about 1.2 ( $M$ =16) to 1.5 ( $M$ =2) dB in terms of performance.

短距离、超低功耗通信的设计和性能分析

我们对在严格的功率限制下运行但在带宽限制下灵活的通信系统感兴趣。我们的方法是考虑收发器中的一些关键元素并优化它们以实现低功耗,而不是优化它们以最小化,例如平均错误概率。这样做的一个明显后果是,系统的高复杂性组件,例如匹配滤波器、采用迭代解码器的前向纠错、相干解调器和带宽高效的调制格式,对于这项研究是不可行的。相反,我们的系统是使用 百万美元 具有非相干检测、优化的两极带通滤波器 (BPF) 和具有硬判决解码的 Reed-Solomon (RS) 代码的 -ary FSK。除此之外,我们表明,通过适当优化 BPF 和 RS 代码的关键参数,我们可以将系统设计得比优化系统复杂得多,并且仅损失约 1.2 ( 百万美元 =16) 到 1.5 ( 百万美元 =2) 性能方面的 dB。
