Antennas & Propagation Society Zoom link will be sent to registrants before the event. Registration:  Next-generation wireless RF systems are expected to contain multi-functional, highly flexible, and tightly integrated front-ends for achieving agile use of the frequency spectrum. In the past decade, this has led to research on filtering antennas, or filtennas, in which the functionality of the antenna and filter is combined into a single highly integrated module that achieves the function of both components with a higher-order transfer function. These filtennas can have improved performance, size, and cost. Furthermore, by incorporating frequency-agility, a filtenna can provide adaptation to changing radio environments. One of the challenges in realizing a reconfigurable filtenna is that two dissimilar elements need to be tuned in tandem. This presentation covers recent developments in the design of reconfigurable filtennas in the S-band (2-4 GHz) and X-band (8-12 GHz). The filtennas are based on using evanescent-mode cavities as the backing for slot antennas. A discussion of available tuning mechanisms and the challenges of going from S-band to X-band is included. Second-order reconfigurable filtenna proof-of-concept prototypes are shown in both frequency bands. The prototype filtennas are created using commercially available printed circuit board materials and tuning elements and measured in an anechoic chamber. The S-band filtenna can continuously tune from 2 to 2.6 GHz while achieving a realized gain between 2.7 to 5.2 dB, respectively. The X-band filtenna demonstrates tuning from 9.6 to 11.1 GHz, with a maximum gain of 5 dB. Overall, with the demonstrated performance, these elements are promising components for future wireless communications and radar systems. Biography: Jessica E.

COURSE DESCRIPTION

Digital Signal Processing (DSP) for Software Radio

Course Summary

This course builds on the IEEE course “DSP for Wireless Communications” also taught by Dan Boschen, further detailing digital signal processing most applicable to practical real-world problems and applications in radio communication systems. Students need not have taken the prior course if they are familiar with fundamental DSP concepts such as the Laplace and Z transform and basic digital filter design principles.

This course brings together core DSP concepts to address signal processing challenges encountered in radios and modems for modern wireless communications. Specific areas covered include carrier and timing recovery, equalization, automatic gain control, and considerations to mitigate the effects of RF and channel distortions such as multipath, phase noise and amplitude/phase offsets.

Dan builds an intuitive understanding of the underlying mathematics through the use of graphics, visual demonstrations, and real-world applications for mixed signal (analog/digital) modern transceivers. This course is applicable to DSP algorithm development with a focus on meeting practical hardware development challenges, rather than a tutorial on implementations with DSP processors.

Now with Jupyter Notebooks!

This long-running IEEE Course has been updated to

include Jupyter Notebooks which incorporates graphics together with Python simulation code to provide a “take-it-with-you” interactive user experience. No knowledge of Python is required but the notebooks will provide a basic framework for proceeding with further signal processing development using that tools for those that have interest in doing so.

This course will not be teaching Python, but using it for demonstration. A more detailed course on Python itself is covered in a separate IEEE Course routinely taught by Dan titled “Python Applications for Digital Design and Signal Processing”.

All set-up information for installation of all tools used will be provided prior to the start of class.

Target Audience:

All engineers involved in or interested in signal processing for wireless communications. Students should have either taken the earlier course “DSP for Wireless Communications” or have been sufficiently exposed to basic signal processing concepts such as Fourier, Laplace, and Z-transforms, Digital filter (FIR/IIR) structures, and representation of complex digital and analog signals in the time and frequency domains. Please contact Dan at boschen@loglin.com if you are uncertain about your background or if you would like more information on the course.

Benefits of Attending/ Goals of Course:

Attendees will gain a strong intuitive understanding of the practical and common signal processing implementations found in modern radio and modem architectures and be able to apply these concepts directly to communications system design.

Pre-recorded lectures (3 hours each) will be distributed Friday prior to each week’s workshop dates.  Workshop / Q&A sessions are 6:00PM – 7:30PM on the dates listed below.

As the electric grid undergoes significant transformations and becomes increasingly affected by more frequent and severe weather events, the resilience and reliability of transmission and distribution systems become extremely important. The advancement of Energy Management Systems (EMS) is crucial for maintaining the reliable operation of power systems. A Phasor Measurement Unit (PMU)-based framework enhances state estimation accuracy, thereby improving the effectiveness of modern EMS applications, such as security assessments. By leveraging synchronized measurements, this framework enhances the reliability and efficiency of EMS, optimizing system operation and performance. The changing energy generation mix, the growth of DERs, and the integration of renewable energy resources at both large scale and individual user level necessitate stronger grid resilience and greater consumer choice. To meet these evolving requirements, enhanced real-time visibility and control of bidirectional energy flows across the distribution grid are essential. The deployment of advanced technologies, such as the Distribution Linear State Estimator (DLSE), is key to addressing these challenges. This presentation will discuss the critical roles of PMU-based EMS and network analysis applications, and DLSE in enhancing the situational awareness, analysis, monitoring, and control of modern transmission and distribution systems, ensuring their resilient and reliable operation.
