期刊Asymptotically Optimal Decision Rules for Joint Detection and source Coding
《IEEE Transactions on Information Theory》Merhav, N.;Dept. of Electr. Eng., Technion - Israel Inst. of Technol., Haifa, Israel
The problem of joint detection and lossless source coding is considered. We derive asymptotically optimal decision rules for deciding whether or not a sequence of observations has emerged from a desired information so...显示全部

期刊Stealing bits from a quantized source
《IEEE Transactions on Information Theory》Cohen, A.S.; Draper, S.C.; Martinian, E.; Wornell, G.W.
We consider 'bit stealing' scenarios where the rate of a source code must bereduced without prior planning. We first investigate the efficiency of source requantization toreduce rate, which we term successive ...显示全部
