Location:
E 103, Okanagan College, 1000 KLO Rd., Kelowna, BC V1Y 4X8 (parking info.)

Talk Abstract: Online video games are interactive competitions among individual players competing in a virtual environment. A Gamers Private Network, or GPNTM, connects players to a common game service across the Internet. In this talk we will describe an experimental, local, and virtualized investigation of the parameters for minimal and stable connection latency in GPNs. Our conclusions isolate the effect of player type and number, activity vs idleness, and router and server virtualization. They provide a clear basis for future modelling and predictive use of latency information in GPNs. Nine Computer Science students in COSC 470 Software Engineering Project course started a related capstone project. They were able to develop a new simulation bot for the Minecraft online game and a new SW engineering prototype.

This work has been funded by NSERC’s College and Community Innovation Program – Applied Research and Development Grant Level-1 (July – December 2014).

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

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.

Speaker Biography: Dr. Gaoyong Luo is a Professor and has been heading the Department of Electronics Information at Guangzhou University. He has a Ph.D. in Electrical Engineering from Brunel University, UK. Since 1998, he has been with Buckinghamshire Chilterns University College and Buckinghamshire New University.

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.
