This paper presents a novel lossless compression technique of the context-based adaptive arithmetic coding which can be used to further compress the quantized parameters in audio codec. The key feature of the new technique is the combination of the context model in time domain and frequency domain which is called time-frequency context model. It is used for the lossless compression of audio cod...

Report Abstract: UHF band passive RFID systems have been steadily adopted by industries leveraging the long range automatic identifications. For the applications which demand large number of readers to be located in a limited geographical area, the interference rejection among readers is important. The coding method, baseband or subcarrier coding, of the tag to reader communication link entails...

In this study, a repeated correlative coding scheme is proposed to combat the inter-carrier interference (ICI) caused by the frequency offset in orthogonal frequency division multiplexing (OFDM) communication systems. This proposed scheme combine two ideas of the well-known methods, which are the coding of adjacent subcarriers with antipodal of the same data symbol (ICI self-cancellation) and c...

SUMMARY The ring F p + uF p + · · · + u k−1 F p may be of interest in coding theory, which have already been used in the construction of optimal frequency-hopping sequence. In this work, cyclic codes over F p + uF p + · · ·+u k−1 F p which is an open problem posed in [1] are considered. Namely, the structure of cyclic code over F p + uF p + · · · + u k−1 F p and that of their duals are derived.
