Joint source-channel coding/decoding (JSCC/JSCD) techniques have become state-of-the-art and one of the challenging research subjects in the spatial communication area. This paper addresses the basic principles of joint source-channel optimal design and classification of various existing JSCC/JSCD methods. It presents a JSCD scheme based on variable-length coding, which is capable of providing reliable resolutions and has shown superior performance compared with the existing ones. The...

Researchers at the Burnham Institute for Medical Research (Burnham) have shown that search algorithms used in digital communications can help scientists identify effective multi-drug combinations. The study, led by Giovanni Paternostro, M.D., Ph.D., was published in the December 26, 2008, issue of PLoS Computational Biology.Using the stack sequential algorithm, which was developed for digital communications, the team of scientists searched for optimal drug combinations. This algorithm can...

Shiron Satellite Communications, a global supplier of broadband VSAT network systems, demonstrated successfully its InterSKY VSAT platform, utilizing a DVB-S2 16APSK modulation over a live satellite in both Ku and C band. The demonstration was performed in Rio de Janeiro at a service provider's teleport facility, using a Brazilian commercial satellite. Shiron announced that 32APSK modulation is also supported by its InterSKY VSAT systems. "Shiron proved its technology leadership...

Researchers are developing advanced computers that can think clearly even when they're bombarded by space radiation. When your computer behaves erratically, mauls your data, or just "crashes" completely, it can be frustrating. But for an astronaut trusting a computer to run navigation and life-support systems, computer glitches could be fatal. Unfortunately, the radiation that pervades space can trigger such glitches. When high-speed particles, such as cosmic rays, collide with the...
