Codec Enabled Audio Communications over IP/Mobile Internet (10/09/2014)

Department of Electronics Information, Guangzhou University, China

Codec Enabled Audio Communications over IP/Mobile Internet

 Time & Date: 5 pm – 6 pm, Thursday, October 9, 2014

Location: EME 1153, UBC, Okanagan Campus, Kelowna, BC

Talk Abstract: The Mobile Internet (by 3G/4G/5G network) is very widely spread today. Audio over Internet Protocol (IP) terminals are increasingly being used in radio operations for streaming of radio programs over IP networks from remote sites or local offices into main studio centers. The IP networks used are invariably well-managed private networks with controlled quality of service, which refers to the ability to reduce delay and jitter over IP. The internet is increasingly also used for various cases of radio contribution, especially over longer distances. Radio correspondents will have the choice in their equipment to use either the Mobile Internet/WiFi or other available IP networks to deliver audio, reaching many millions of people using terminals such as office desktops, personal digital assistants (PDAs) and mobile phones. With the increase of bandwidth (data rates) available for mobile internet user, on-line conversation by audio over IP instead of voice over IP is now possible, which offers better quality of service. It is expected that audio over IP systems will be used more and more for live IP streaming. However, with very few exceptions, IP equipment from one manufacturer has until now not been compatible with another manufacturer’s unit. Some of the audio over IP units are still in a somewhat immature, more or less prototype stage but further development continues. The requirements for interoperability are based on the use of RTP over UDP for the audio session and SIP for signaling. The packet payload audio structure is defined for commonly used audio formats in radio contribution. Four mandatory codec formats are specified: G.711, G.722, MPEG Layer II and linear PCM. Other audio formats can be used as well, but the latency is a big concern. The audio encoding itself introduces delays from milliseconds for PCM to more than hundreds of milliseconds for some bit-rate reduced coding formats. In the case of a two-way conversation, the total round trip delay should be kept as low as possible, because otherwise a conversation becomes difficult, especially when non-experienced reporters or the general public are interviewed. In addition, the IP network itself has a delay, from a few tenths of milliseconds in well managed networks up to 500ms or more on very long distances over the internet or satellite links. This talk will address the continuous development of IP networks combined with more sophisticated audio over IP terminals in the era of mobile internet. Connections over the internet with different types of telephony and professional units for broadcasting will improve telephone audio quality and worldwide access to Reporters by the newly developed WiFi terminals using very low delay audio coding technology, which results in IP audio codecs that can provide rock solid studio to transmitter link (STL), remote broadcast and audio distribution solutions. Small handheld units and also software codecs in mobile phones will provide very efficient tools for users. This talk is based on the collective inputs from many manufacturers, and long term research on audio communications over IP and wireless channel.

Scalable parallel programming: hardware, algorithms and applications (08/25/2014)

Scalable parallel programming: hardware, algorithms and applications

Time & Date: 5pm – 6pm, Monday, August 25th, 2014
Location: EME 1202, UBCO, Kelowna Campus, Kelowna

Talk Abstract: We will present and explain the Bulk-Synchronous Parallel (BSP) model of
parallel computation. BSP was invented in 2009 by Leslie Valiant and has been applied to almost every possible parallel algorithm, parallel hardware and parallel software application. BSP allows a clean and portable understanding of how parallel hardware can «couple» efficiently or not with big data and large-scale simulations.
We outline categories of applications where infinite scalability is either, easy, conditional and
complex or mostly impossible. Measured machine parameters allow performance prediction for computations of unlimited size in many application areas.

Chasing Channels- Adaptive Codebooks for Limited Feedback MIMO (11 August 2014)

Chasing Channels- Adaptive Codebooks for Limited Feedback MIMO

Time & Date: 10:30am-11:30pm, August 11, 2014

Location: EME 1121, UBC Okanagan campus

Talk Abstract:Multiple-input multiple-output (MIMO) systems have received considerable attention over the last two decades owing to the improvements in link throughput and/or the reliability of signal reception. In order to achieve the full capacity gains, channel state information is required at the transmitter, thus necessitating feedback of this information from the receiver to the base station. Given the multi-carrier nature of 4G systems, this feedback overhead is restricted to a few bits per subcarrier. Consequently, the performance of limited feedback closed-loop MIMO systems is very sensitive to the codebooks used to achieve such channel quantization.

Codebooks in current standards, such as LTE, were optimized for independent identically distributed Rayleigh fading channels, whereas realistic propagation environments exhibit both temporal and spatial channel correlations. In this talk we will demonstrate the inefficiency and performance loss of standard codebooks in realistic channel models (such as WINNER II), thus motivating adaptive codebook techniques. We will present methods for perturbing the standard codebooks, specifically focusing them around the channel and following the channel trajectory throughout transmission – thus significantly reducing the quantization errors. Blind adaptation methods, i.e. without introducing additional feedback requirements, will be presented.

Registration is opened: https://meetings.vtools.ieee.org/meeting_view/list_meeting/22019

Talk Abstract: The world of HIgh Performance Computing (HPC) is one of vast numbers: tens of thousands of compute nodes clustered together, petabytes of shared storage, and kilometres of network cables.  The demands HPC places upon storage systems are the most extreme of any other computing discipline.  In this talk, I will be outlining the specific requirements of HPC storage systems, and delve into the architecture of “Lustre”: an open source parallel distributed file system used by the majority of the top 100 supercomputers.  I will also be talking about the future of HPC file systems and how Big Data is adopting HPC file systems to improve performance.

Speaker Biography: Doug Oucharek is the manager of the Lustre Core Development group at Intel.  He was pulled into Intel as part of an acquisition of a startup supporting Lustre called “Whamcloud”.  Prior to working for Whamcloud, he spent over 25 years working on various networking products at several companies including Nortel, Motorola, IBM, HP, and Broadcom.  Doug works and lives in Naramata, BC, Canada.
