Air and space-based earth-observing sensors are instrumental in monitoring natural phenomenon. And space-aeronautics coordinated observation can complement each other. However, current operations involve “stovepipe” systems in which inefficiencies are inherent. Considering the difference between satellite task planning model and airplane task planning model, a coordinated optimization model of space-aeronautics...
We describe a highly scalable parallel arithmetic coder for Markov inputs suitable for implementation on modern multi-core processors. The algorithm divides the input into interleaved sub-sequences which can be then processed independently on different processing units using LDPC-based Slepian-Wolf coding. Experimental simulations show good scalability of the proposed algorithm while also maintaining...
