In the past year, our broad program of research has continued to explore efficient solutions fundamental problems of communication for wireless and wired networks, exploiting interrelated perspectives from communication theory, information theory, signal processing theory, and control theory. As part of this work novel applications chaos and fractal geometry are also being explored. As one component of the research, we have continued to develop novel multiscale methods for analyzing packet switched data networks with bursty traffic exhibiting fractal behavior. These methods have also led to the development of complementary new multiscale traffic management strategies for more efficiently routing and serving packets in such networks. These new results are described in detail in the Ph.D. thesis of Warren Lam completed during this reporting period. In other aspects of the ongoing research, we developed additional results on the use of nonlinear dynamics, chaos, and solitons in the design of innovative analog error protection codes for communications applications, and developed new very low complexity adaptive coding techniques for exploiting the availability of feedback in unknown, time varying wireless communication networks. As a final component of the research, we have continued to develop promising new and bandwidth-efficient classes of time, frequency, and space diversity strategies for single and multiuser wireless communication in multipath fading environments.
