CONACYT: Design and Implementation of a Wireless Communication System using BiCMOS Technologies

本提案的主要目标是使用统一的方法识别、表征、建模和设计无线系统应用中必不可少的算法和设备。这涉及到从系统角度一直到晶体管级实现的（自上而下）分层设计。在系统架构、BiCMOS电路实现、成本、功耗和不同层次的性能之间的权衡将被确定。这项研究将产生重要的实际结果，形成许多无线通信产品的基础，特别是那些用于即将到来的个人通信系统（PCS）和工业，科学和医疗（ISM）频段上的通信。在以集成电路形式构建完整的无线通信产品与混合（带有片外组件）之间的权衡将是拟议研究的关键组成部分。本提案中提出的工作包括理论、软件仿真和硬件实现。该方法的独特之处在于两个在通信和微电子电路方面取得公认成就的小组的协调努力。提出这个项目的两个机构的教师和研究生之间的互动是很有希望的。德克萨斯农工大学将在通信系统架构、多址技术（即CDMA、TDMA等）、信号处理算法、混频器以及有源和无源滤波器方面做出贡献。INAOE的贡献将主要集中在关键模块的BiCMOS电路设计上。这些模块包括前端低噪声放大器（LNA）、功率放大器、信道编码器/解码器和相关器。首先将通过软件仿真（包括权衡、重要构建模块的硅芯片原型的实验验证以及一些系统应用结果）来验证所提出设计的可行性和性能。本提案研究的成功结论将为设计无线通信系统，特别是在ISM频段上运行的pc和未经许可的设备提供实用、统一的设计方法。预计系统、构建块和硬件级别的贡献以及它们之间的相互关系。这项研究将对我们大学无线研究和教育的基础设施产生重要影响，因为相当多的学生已经参与其中。这些学生的资金不仅可能来自本提案所要求的支持，而且还将来自目前的支持，超过50万美元，来自德州农工大学工程学院和电气工程系，以及德州仪器公司，在未来三年内。拟议研究的实用性和相关性是基于实质性的工业联系，以及学术界和大学之间强有力的思想交流。＊＊＊

9613722 Sanchez-Sinencio The main goal of this proposal is to identify, characterize, model, and design algorithms and devices that are essential in wireless system applications, using a unified approach. This involves a (top-down) hierarchical design all the way from the system point of view, to the transistor level implementation. Tradeoffs between system architecture, BiCMOS circuit implementations, cost, power consumption, and performance at different levels will be identified. This research will yield important practical results that form the basis for many wireless communication products, and specifically those to be used for the upcoming personal communication systems (PCS) and in communication over the industrial, scientific and medical (ISM) bands. The tradeoffs in building complete wireless communication products in integrated circuit form, versus hybrids (with off-chip components) will be a key component of the proposed research. This work proposed in this proposal encompasses theory, software simulation, and hardware implementations. The uniqueness of the approach is based on the coordinated effort of two groups with proven accomplishments in communications and microelectronics circuits. Heavy interaction between both faculty members and graduate students from the two institutions proposing this project is expected. The Texas A&M University contribution will be in the communication system architectures, multiple-access techniques (i.e. CDMA, TDMA, etc.), signal processing algorithms, mixers, and active and passive filters. The INAOE contribution will be mainly in the BiCMOS circuit design of key building blocks. These blocks include the front-end low noise amplifier (LNA), power amplifiers, channel encoders/decoders, and correlators. The feasibility and performance of the proposed designs will be verified first by software simulation involving tradeoffs, experimental verification b silicon chip-prototypes of important building blocks, and some system applications resul ts. A successful conclusion of this proposal research will lead to practical, unified design methodologies for designing wireless communication systems, especially those for PCS and unlicensed devices operating in the ISM bands. Contributions at the system, building block, and hardware levels and their interrelations are anticipated. This research will have an important effect on the infrastructure of wireless research and education in our universities, since a significant number of students are already involved. Funding for these students will come not only potentially from the support requested in this proposal, but also from present support, exceeding half a million dollars, from the College of Engineering and the Department of Electrical Engineering at Texas A&M University, as well as from Texas Instruments, over the next three years. The utility and relevance of the proposed research is based on substantial industrial ties, and strong exchange of ideas between academia and university. ***
