High-throughput multiple-input multipleoutput systems for in-home multimedia streaming

Performance of multiple-input and multipleoutput orthogonal frequency and code division multiplexing systems in fading channels

In broadband downlink transmission, orthogonal frequency-division multiplexing (OFDM) combined with code-division multiple access (CDMA) is a prospective technique for high-data rate transmission in future wireless communication systems. By adding spatial diversity, multiple-input and multiple-output orthogonal frequency and code division multiplexing (MIMO-OFCDM) offers superior performance re...

Very High Throughput (VHT) Multi-User Multiple Input Multiple Output (MU-MIMO) Communication in 802.11ac

An Architecture for Streaming Control in Distributed Multimedia Systems

The development of distributed multimedia systems can benefit from the availability of a flexible infrastructure able to support the interoperation between components, and capable of dynamically adapt itself to the system configuration. CORBAcompliant distributed multimedia applications permit a high level of accessibility, decentralization and interoperability with other components. However, a...

Liquidsoap: A High-Level Programming Language for Multimedia Streaming

Generating multimedia streams, such as in a netradio, is a task which is complex and difficult to adapt to every users’ needs. We introduce a novel approach in order to achieve it, based on a dedicated high-level functional programming language, called Liquidsoap, for generating, manipulating and broadcasting multimedia streams. Unlike traditional approaches, which are based on configuration fi...

Maximum Sustainable Throughput Prediction for Large-Scale Data Streaming Systems

In cloud-based stream processing services, the maximum sustainable throughput (MST) is defined as the maximum throughput that a system composed of a fixed number of virtual machines (VMs) can ingest indefinitely. If the incoming data rate exceeds the system’s MST, unprocessed data accumulates, eventually making the system inoperable. Thus, it is important for the service provider to keep the MS...
