Long timescale time-variant behavior of digital modems.

Join the IEEE North Saskatchewan Section (NSS) Circuits and Systems / Signal Processing / Communications (CAS/SP/COM) Joint Chapter for an engaging technical presentation featuring Calian Advanced Technologies and its cutting-edge innovations. The session will comprise an overview of Calian products and services, with a focus on its software defined radio (SDR) platform. This platform is used by Calian to implement a range of digital modems. Through a series of case studies, we’ll explore how digital radio architectures can become time-variant—and why this can cause failures that are especially challenging to detect and test. Linear time-invariant systems are the starting point for this type of analysis because linear time-invariant properties allow for reasonably straight forward mathematical modeling. More complex real-world designs often break these properties, in some cases intentionally in order to allow better performance to be achieved, and in some cases unintentionally. When time-variant behavior occurs over long timescales, it can be extremely challenging to test. Ideally, this type of behavior can be predicted early in the design process and then mitigated at the architecture level. The case studies provide examples of four classes of real-world long time variance in a digital modem: intrinsic-design, intrinsic-defect, extrinsic-design, and extrinsic-defect. 📅 Date: September 11 🕓 Time: 4:00 – 6:00 PM 📍 Location: The Candle Room, Innovation Place Whether you are a researcher, engineer, student, or professional in communications systems, this event will deliver valuable insights into the complexities of SDR technology and practical approaches to overcoming them.
