Multirate digital signal processing techniques have been developed in recent years for a wide range of applications from wireless and satellite communication systems to speech and image compression, including high performance audio and video, statistical and adaptive signal processing, and multimedia, among others. The main advantage of multirate systems is rooted in the computational efficiency based on the ability to use different sampling rates simultaneously in the same system. The wireless communication industry has experienced exceptional growth in the past decade. There has recently been a paradigm shift in the way next generation wireless communication systems are being designed.

The important feature of future wireless transceivers regards re-programmability from the antenna to baseband: this is key to the design of multi-mode and scalable multistandard transceivers able to support an open software model. Software defined radio (SDR) aims to support these features by considering them as essential design requirements. Cognitive radio (CR) is an extension of the software radio concept encompassing the adoption of autonomous and intelligent decision making as compared to traditional radio design. In both these promising technologies for future communication systems, SDR and CR, multirate systems perform key signal processing operations efficiently.

The age of 5G communication is approaching. You are invited to participate in the 2017 International Conference on Circuits, Devices and Systems(ICCDS 2017) in Chengdu, China, September 5-8, 2017. ICCDS is sponsored by IEEE, UESTC and National Taiwan University, it will provide a premier interdisciplinary platform for researchers, practitioners and educators to present and discuss the most recent innovations, trends, and concerns as well as practical challenges encountered and solutions adopted in the fields of Circuits, Devices and Systems.
