Upcoming technical seminar and announcements

We will be holding our monthly seminar series in-person, on Thursday February 13. Light meals will be served (free of charge, registration required).

Time (Eastern Standard Time):

6:00 PM:  Networking starts
6:15 PM:  Light meals served.
7:00 PM:  Seminar starts

Speaker:  Christian Reimer, PhD (HyperLight Corporation)

This presentation will provide an introduction into integrated photonics in thin-film lithium niobate (TFLN) photonics and its applications, including technical status and ongoing development. Over the past years, TFLN has transitioned from a research-centered new material platform to becoming the leading platform to provide practical solutions for next generation applications. In particular datacom, telecom and high-performance applications such as radio-over-fiber and measurement and test can benefit from TFLN attributes such as ultra-high electro-optic bandwidths, low driving voltages, compact size and cost-effective volume production.

Biography:

Dr. Christian Reimer is a physicist and entrepreneur working in the fields of nonlinear optics, integrated photonics and quantum optics. He received graduate degrees from the Karlsruhe Institute of Technology in Germany, Heriot-Watt University in Scotland, and the National Institute of Scientific Research in Canada. He then worked as a postdoctoral fellow at Harvard University, before becoming Co-Founder and Chief Architect of HyperLight Corporation. HyperLight, a Venture-Capital funded scale-up, is specialized on scalable integrated lithium niobate technologies for ultra-high performance photonic solutions.

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.

Kick-off / Orientation:  Thursday, February 20, 2025

Topics / Schedule:

Class 1: Thursday, February 27:  DSP Review, Radio Architectures, Digital Mapping, Pulse Shaping, Eye Diagrams

Class 2:  Thursday, March 6:  ADC Receiver, CORDIC Rotator, Digital Down Converters, Numerically Controlled Oscillators

Class 3: Thursday, March 13:  Digital Control Loops; Output Power Control, Automatic Gain Control

Class 4: Thursday, March 20:  Digital Control Loops; Carrier and Timing Recovery, Sigma Delta Converters

Class 5: Thursday, March 27:  RF Signal Impairments, Equalization and Compensation, Linear Feedback Shift Registers

Speaker’s Bio:

Dan Boschen has a MS in Communications and Signal Processing from Northeastern University, with over 25 years of experience in system and hardware design for radio transceivers and modems. He has held various positions at Signal Technologies, MITRE, Airvana and Hittite Microwave designing and developing transceiver hardware from baseband to antenna for wireless communications systems and has taught courses on DSP to international audiences for over 15 years. Dan is a contributor to Signal Processing Stack Exchange https://dsp.stackexchange.com/, and is currently at Microchip (formerly Microsemi and Symmetricom) leading design efforts for advanced frequency and time solutions.
