    In high-speed OFDM transmission, inter-block interference degrades the system performance when the impulse response length of a frequency-selective channel is longer than expected. This article explains the concept and specific methods of channel shortening, which uses time-domain linear filters to reduce the effect of inter-block interference. First, we describe channel-shortening methods for the case where the channel is known to the receiver. Next, we introduce blind channel-shortening methods, which determine filters without pilot symbols or knowledge of the channel.

  • Evolution of Symmetric-Key Cryptosystems

    Cryptosystems are one of the most important tools for information security, and symmetric-key ciphers are widely used. Cryptographers have developed and applied various cryptanalysis techniques to guarantee security. If no one can attack a symmetric-key cipher, the cipher is regarded as secure. In other words, it is possible that a symmetric-key cipher will suddenly be broken. In this article, we introduce the history of the creation and destruction of symmetric-key ciphers. We also review a new cryptanalytic tool that was used to theoretically break the symmetric-key cipher MISTY1.

    Variable digital filters are frequency-selective digital filters whose frequency characteristics, such as the cutoff frequency and bandwidth, can be controlled in real time. Variable digital filters are used in a number of fields such as telecommunications, speech processing and audio processing. This paper discusses recent research activities on variable digital filters, focusing on the problems of design and realization. In addition, research results on variable digital filters regarding their application to adaptive signal processing are also reviewed.
