Probability and Random Processes

​These notes cover basic probability theoretic concepts and stochastic processes. From these, the classical estimation theory concepts underlying classic and Bayesian estimation are developed. Finally, the mean-square filtering concept is extended to the formulation of the Kalman filters and its modern varieties, such as the unscented Kalman filter. To access the full document, please contact us.

Fundamentals of Wireless Networks

This presentation discusses the physical layer foundations for wireless radio networks. Network communications layers are then explained with a strong emphasis on the medium access layer. Here, the traditional random access protocols derived from the original ALOHA method, as well as modern enhancements are discussed. To use or print this document, please contact us.

Waveform Communications

These notes walk through the development of basic digital communications principles, such as matched filtering, Nyquist signaling, multi-level modulation, and orthogonal-frequency division multiplexing (OFDM) from basic linear systems theory, in particular the fourier series. The latter is also used to derive the sampling theorem, the fourier transform, and some of its main theorems. To use or print this document, please contact us.

Check out our experimental FPGA Radio design!

Our FPGA-based radio system is based on a Matlab/Simulink to RTL design flow, implemented in Xilinx’ Vivado Suite. Downloadable code and interface modules to the Analog Devices radio card are readily available and can be adapted to individual needs. Our base system is an OFDM radio operating at a sampling rate of 100 MHz, complete with frame acquisition and channel estimation functionalities.

Introduction to Shannon's Channel Capacity

Watch Dr. Schlegel discuss the fundamental principles of modern error control coding. He reviews the information theoretic basics of error control coding from Shannon capacity formula to the Shannon bound and discusses fundamental transmission limits expressed by the channel coding theorem and highlight the accomplishments of error control coding over the last half century. Contact us for your customized course needs!
