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...

The previous schemes are introduced, including traditional network coding (NC) scheme, physical-layer network coding (PNC) scheme, soft network coding (SNC) scheme and pseudo physical-layer network coding (PPNC) scheme. As an improved scheme of PNC, PPNC does not need synchronization mechanism, however its BER performance gets worse due to the hard decision applied on the relay node. The new pr...

We propose a trellis-coding scheme for which large free distances and low decoding complexities can be easily achieved. The proposed trellis-coding scheme is a generalization of the trellis-coding scheme proposed by Hellstern. With the proposed trellis-coding scheme, we have the flexibility of controlling the decoding delay.

This paper presents a generic, scalable, efficient shape coding scheme for scalable object-oriented visual texture. The base-layer coding scheme used is similar to the binary CAE coding scheme adopted in MPEG-4 video. The proposed scheme introduces a new set of generic contexts to efficiently encode (predict) enhanced shape layer based on the lower spatial layer using a context-based arithmetic...
