The Scalable High Efficiency Video Coding (SHVC) has been proposed to improve the coding efficiency. However, this additional extension generally results an important coding complexity. Several studies were performed to overcome the complexity through algorithmic optimizations that led to an encoding time reduction. In fact, mode decision analysis is imperatively important in order to have an i...

It is well known that orthogonal coding can be used to approach the Shannon capacity of the power-constrained AWGN channel without a bandwidth constraint. In this paper, I show that it is possible to do this using a semi-orthogonal variation of pulse position modulation that is sequential in nature — bits can be “streamed out” without having to buffer up blocks of bits at the transmitter. Maxim...

Interconnect will be a major bottleneck for deep sub-micron technologies in the years to come. This dissertation addresses the communication aspect from a power consumption and transmission speed perspective. A model for the energy consumption associated with data transmission through deep sub-micron technology buses is derived. The capacitive and inductive coupling between the bus lines as wel...

This paper investigates the feedback stabilization problem for networked control systems (NCSs) with unbound process noise, where sensors and controllers are connected via noiseless digital channels carrying a finite number of bits per unit time. A sufficient condition for stabilization of NCSs, which relies on a variable-rate digital link used to transmit state measurements, is derived. A lowe...

This paper addresses networked control problems which arise in the coordinated motion control of autonomous and semiautonomous mobile agents, where the sensors and controllers are geographically separated and connected by digital communication channels carrying a finite number of bits per unit time. Different from the existing results, this case with quantized output measurements and limited da...
