Summary: This is a 2-part course. The Advanced Protocols for Wireless Ad-hoc Networks will illustrate that in Ad-Hoc networks where there is no underlying fixed infrastructure, tasks such as network self-organization, mobility management, adaptive route detection for unicast and multicast applications, and provisioning of Gateway functionality to interconnect the ad-hoc network to the rest of the Internet space must be handled according to rules that are unique to the ad-hoc nature of the system. Topics related to support of QoS at various network layers will also be discussed, with emphasis on layers 2, 3, and 4 of the network. We will investigate the performance of these protocols in terms of their level of scalability to different sizes, and traffic loads. Topics of security will also be discussed.
Summary: This course will begin by providing a historical perspective of Hybrid Electric Vehicles. Next an overview of the Toyota input split e-CVT fundamentals and operation, and the Ford input split e-CVT fundamentals and operation will be presented. The course will then focus on e-CVT dynamics. Electric variator theory and input split examples will be provided followed by a presentation of GM-Allison compound split fundamentals and operation. Next, Compound split dynamics will be presented followed by the Timken compound split system and the Renault compound split system. Finally, energy storage system technologies will be presented as well as a summary and cost illustrations. After completing this course you should be able to develop an understanding of: The history of Hybrid Electric Vehicles; Electric veriator theory; Energy storage system technologies.
Summary: This is a 2-part module. Introduction to Wireless Ad-hoc Networks will provide a technical overview and introduction to the topic of wireless ad-hoc networks. Wireless Ad-hoc networks will be defined. Major requirements and challenges of wireless ad-hoc networks will be covered. The solution space, and related technologies at different layers will be discussed.
Summary: In the context of a rich scattering environment, employing multiple antennas at the transmitter and receiver provides a capacity increase that is linear in the minimum of the number of transmit and receive antennas. This seminal result of Foschini & Gans and Teletar has opened the new field of space-time communications. In this tutorial we introduce the key concepts of space-time communications, focusing on transmission in a quasistatic channel for which a good estimate of channel state information is available at the receiver but not the transmitter. Both low-latency (trellis codes) and high-latency (LDPC codes) solutions will be presented. After completing this course you should be able to develop an understanding of: Capacity potential provided by multiple antennas; Layered transmission systems such as DBLAST; Rank and determinant criteria for space-time trellis codes with good average performance in Rayleigh fading; The Alamouti construction and the theory of orthogonal designs; Universal space-time trellis codes for environments where fading is not Rayleigh; Space-time communications using LDPC codes.
Summary: This tutorial will cover how to optimize transmission of OFDM by taking a look at: Pulse Shaping, Guard Time; Coded OFDM; Peak Power Problem and Remedies; Multicarrier CDMA.
