Webcast: LTE Broadband Wireless Access
Wednesday, February 3rd, 2010New Course on Modulation and Signal Formats
Tuesday, February 2nd, 2010Instructor Earl McCune Jr. will be presenting a new course on "modulation without math" - or more precisely, "modulation without triple-integrals." This three day lecture and demonstration based course is designed to provide all participants with a physically intuitive understanding of wireless communication signals and why they work the way they do. With the growing impact of wireless communications on the basic operation of society, the need for a more general understanding of the basis for this technology is more important than ever. The course approaches wireless communications signals through the window of physics and physical principles. While a solid understanding of the mathematical theory is essential for detailed system design and analysis, the fundamental choices in system application and approach are often best approached physically. Dr. McCune will not shun math in this presentation, but instead of using math as the presentation base he will instead use it as a follow up illustrator of the principles discussed. The three days cover all of the major modulations used in digital wireless communication, including ASK, FSK, PSK, QAM, and OFDM. System principles such as an extensive discussion of the Shannon Capacity Limit, plus the physical basis of Nyquist filtering, are included. Important system parameters and analysis tools which are common to any modulation type are presented and demonstrated.

Radar Systems Basic Concepts
Tuesday, February 2nd, 2010
Below is a brief overview of the information featured in last month’s webcast on Radar Systems.
Radar measurements can be divided into two categories: range/speed and azimuth/elevation. Range and speed measurements are relatively simple and accurate. If the target is moving towards or away from the radar antenna, the reflected signal will experience a doppler shift. This shift can be measured and the speed calculated in a straightforward manner. To measure the range of a target, a pulsed signal is sent and the time delay for the reflection is measured. Again, the range can be calculated in a straightforward manner.
