The use of block codes is a well known error-control technique for reliable transmission of digital information over noisy communication channels. However, a practically implementable softinput soft-output (SISO) decoding algorithm for block codes is still a challenging problem. This thesis examines a new decoding scheme based on the soft-output Viterbi algorithm (SOVA) applied to a sectionaliz...

The performance of brain-machine interfaces (BMIs) that continuously control upper limb neuroprostheses may benefit from distinguishing periods of posture and movement so as to prevent inappropriate movement of the prosthesis. Few studies, however, have investigated how decoding behavioral states and detecting the transitions between posture and movement could be used autonomously to trigger a ...

Video coding systems may greatly differ from each other, as they consist of complicated functional modules and each module can be realized by using different techniques. For the interoperability in communication, video coding standards are developed to restrict various video coding systems, such that manufacturers can successfully interwork with each other by producing compliant encoders and de...

Neural machine translation has shown very promising results lately. Most NMT models follow the encoder-decoder framework. To make encoder-decoder models more flexible, attention mechanism was introduced to machine translation and also other tasks like speech recognition and image captioning. We observe that the quality of translation by attention-based encoder-decoder can be significantly damag...
