项目摘要

With the exponential increase in data consumption world-wide, the corresponding increase of associated power consumption in wireless communication systems is receiving significant attention and concern. This research effort examines wireless communication performance techniques and limits when simple low-power devices are used to transmit and receive signals. These devices, because of their simplicity, are constrained to transmit and receive "one bit" of information, and with extremely low power consumption. However, many of them can be used together and at very high speeds, giving an overall high effective data rate. The effort examines the potential power advantages of using such devices over conventional devices that are more capable but have much higher power consumption. The project pushes the boundaries on many areas of traditional linear systems and circuit theory, and will be integrated into undergraduate and graduate course offerings in linear systems, digital signal processing, circuit design, and microwave engineering. The results will be used to encourage discussion about how high data rates need not require a large power budget.The design of wireless communication systems that rely on classical linear-system techniques runs into difficulties with high power-consumption of circuits at carrier frequencies above 20 GHz and with bandwidths above 2 GHz. Linear amplifiers, mixers, and high-speed analog-to-digital converters, and digital-to-analog converters in the transceiver chains become inefficient and expensive. This research effort examines wireless communication performance limits and techniques when a novel energy-efficient "transceiver cell" is used for the air interface. The transceiver cell exploits nonlinearities in its devices and circuits to obtain very low power consumption and ease of fabrication in a variety of technologies for wide bandwidths and at very high carrier frequencies. The cell comprises a transmitter and receiver capable of modulating and demodulating a single bit per symbol. The effort is transformative because it looks at maximizing bits/(second-Hz-Watt) in the trade-off of the performance of each cell versus the number of cells in a power-constrained system, by applying concepts from neural-networking systems of low-power nonlinear ``computational cells''.

随着世界范围内数据消耗的指数增长，无线通信系统中相关联的功耗的相应增长正受到显著的关注和关注。这项研究工作探讨了无线通信性能技术和限制时，简单的低功耗设备用于发送和接收信号。这些设备，因为它们的简单性，被限制为发送和接收“一位”的信息，并且具有极低的功耗。然而，它们中的许多可以一起使用并且以非常高的速度使用，从而提供整体高有效数据速率。这项工作考察了使用此类设备与功能更强但功耗更高的传统设备相比的潜在功率优势。该项目推动了传统线性系统和电路理论的许多领域的界限，并将整合到线性系统，数字信号处理，电路设计和微波工程的本科和研究生课程中。结果将用于鼓励讨论如何高的数据速率不需要一个大的功耗budget.The无线通信系统的设计，依赖于经典的线性系统技术运行在20 GHz以上的载波频率和2 GHz以上的带宽的电路的高功耗的困难。收发器链中的线性放大器、混频器和高速模数转换器以及数模转换器变得低效且昂贵。这项研究工作探讨无线通信性能的限制和技术时，一种新的节能“收发器单元”用于空中接口。收发器单元利用其器件和电路中的非线性，以获得非常低的功耗，并且易于在用于宽带宽和非常高的载波频率的各种技术中制造。该小区包括能够调制和解调每符号单个比特的发射机和接收机。这项工作是变革性的，因为它着眼于通过应用低功率非线性“计算细胞”的神经网络系统的概念，在功率受限系统中每个细胞的性能与细胞数量的权衡中最大化比特/（秒赫兹瓦）。
