Communication Systems
A CCS research area

Areas of Research

The mission of the Communication Systems group is to advance the state-of-the-art in media storage and delivery. Exploring the recent advancement in Signal Processing, Data Compression, Information Theory, Communication Theory and Practice, and Distributed Network and System, we work to improve users' every day life experience with stored media and media communication through a variety of Microsoft products. The research areas of the Communication Systems group include:

Projects

• Information Coding. We have worked on all forms of information coding, including audio, image, video, and graphic compression, as well as advanced media compression techniques, such as Scalable Media Compression, Multi Description Coding, Interactive Compressed Media Browsing, Distributed Media Compression and Network Coding. 
• Real Time Audio/Video Conferencing. We have worked on algorithms, protocols, systems and infrastructure that improve the quality of experience of Real-Time Audio/Video Conferencing.
• Network Media Delivery. We have developed optimization framework and algorithms that maximize the rate-distortion performance of media delivery and audio/video conferencing.
• Peer-to-Peer Media Delivery. We have investigated the user of peer-to-peer system to improve the media delivery experience.
• Wireless Communication.  We have explored the use of advanced wireless communication technology for media delivery and communication.
• Distributed Storage. We have investigate the use of erasure coding and de-duplication technology in distributed storage systems.
• Security.  We have developed PRU (Password Re-Use) antiphishing technique.

Product Group Partners and Friends

• We have worked with many Microsoft product group partners and friends to deliver our technologies to the users.
