In this paper, we propose a serially concatenated turbo-encoded faster-than-Nyquist signaling (FTNS) transceiver that takes into account FTNS-specific colored noise effects. The proposed low-complexity receiver carries out soft-decision frequency-domain equalization with the aid of the minimummean square error criterion while whitening the colored noise.(More)
This paper focuses on improving the cipher strength of a particular ubiquitous processor HCgorilla. The reason why this is called the ubiquitous processor is because it progresses the overall status of ubiquitous and processor techniques. Ubiquitous computing is really a leading edge trend of next generation information and communication technologies. One(More)
Emergent ubiquitous environment requires power conscious strong security, high performance, high precision, and real time responsibility. With respect to this view point, a particular ubiquitous processor, HCgorilla is really eligible. This processor covers small scale for mobility and parallelism for Java-based media processing and hardware cryptography(More)
Power conscious strong security and multimedia reality are demanded for the construction of emerging ubiquitous environment. Since multimedia computing requires high performance, high precision, and real time responsibility, the hardware approach or VLSI implementation of sophisticated strategies is one of the most promising solutions to satisfy those(More)
