We consider data-streaming from an access point to multiple receivers, which is modeled as packet erasure channel. A simple network coding is shown to achieve larger rate region than without network coding, using minimal control information. The performance is characterized exactly using state transition graph. The scheme is then mapped to an information theoretic formulation for broadcast channel...
Distributed video coding (DVC) technology is investigated and payed more and more attentions in wireless video applications because of characteristics of its encoder with low-complexity and decoder with high-complexity. Its coding types can be sorted the key and Wyner-Ziv frames, key frames are with conventional intra-coding mode, Wyner-Ziv frames are coded by an encoder that is composed of quantizer...
This paper studies efficient complex valued matrix manipulations for multi-user STBC-MIMO decoding. A novel method called Alamouti blockwise analytical matrix inversion (ABAMI) is proposed for the inversion of large complex matrices that are based on Alamouti sub-blocks. Another method using a variant of Givens rotation is proposed for fast QR decomposition of this kind of matrices. Our solutions...
