This course provides a system design approach for wireless digital transceivers, radar, and cognitive and adaptive processes to enhance the designs for both commercial and military sectors, allowing a broad spectrum of readers to understand the topics clearly. It covers a wide range of data link communication design techniques, including link budgets, dynamic range and system analysis of receivers and transmitters used in data link communications, digital modulation and demodulation techniques of phase-shift keyed and frequency hopped spread spectrum systems using phase diagrams, multipath, gain control, an intuitive approach to probability, jamming reduction method using various adaptive processes, error detection and correction, global positioning systems (GPS) data link, satellite communications, direction-finding and interferometers, plus a section on broadband communications and home networking including Link 16, JTRS, military radios, and networking.
Included in this course are several techniques to improve the performance and adapt to the changing environment of interference, jamming, noise and other system changes. These adaptive and cognitive techniques use various processes to improve the designs by adapting, predicting and making modifications of the capabilities of the wireless system. This seminar addresses multiple cognitive functions and capabilities at multiple levels including an overall cognitive system approach to reduce the effects of the environment. It covers a wide range of cognitive techniques, including cognitive radios, dynamic spectrum access DSA, adaptive power control, adaptive modulation, dynamic antenna techniques using AESAs, cognitive antennas and MIMO, adaptive filters, adaptive networks, learning and reasoning, and total cognitive systems.
This course also covers basic radar designs, radar and radar range equations, modulation, range ambiguity and pulse compression, types of radar, pulse shaping, clutter, two-way power link budget, range resolution, threshold for Probability of Detect and Probability of False Alarms, MTI, blind speeds, Monopulse, SAR and weather radar.

This course will be of interest to RF, analog, digital, systems and software engineers and managers who are interested in the field of communications of all types of wireless systems, radar, and adaptive and cognitive techniques for both commercial and military use. This applies to both those that want to gain an understanding of wireless digital communications, radar, and cognitive techniques and those that are experienced engineers that want to capture an intuitive approach and solidify their understanding of these basic principles. An electrical engineering background (BSEE or equivalent practical experience) is recommended but not required. From this course you will learn how to evaluate and develop the system design for digital communication transceivers including spread spectrum systems, radar systems and basic principles, and learn to incorporate adaptive and cognitive techniques that enhance the connections through changing interference, jamming and noise.
This seminar provides the student with a firm foundation and understanding of digital communications, radar and adaptive and cognitive processes that will be invaluable for system design, analysis and tradeoffs of these systems. Several examples and step processes are discussed to determine the optimal solutions and tradeoffs between the many cognitive capabilities. Many of these design techniques can be applied for both communication and radar links including link budgets, modulation, detection, pulse shaping, interference mitigation, antennas, search and tracking algorithms, multi-use and band sharing, directional search, acquisition and closed-loop tracking, and many more. Also included are techniques to use radar systems for communications using PCM/PPM. In addition, direction finding DF using radar is discussed along with SATCOM radar and frequencies.
