On the Dispersions of the Gel'fand-Pinsker Channel and Dirty Paper Coding
This paper studies second-order coding rates for memoryless channels with a state sequence known non-causally at the encoder. In the case of finite alphabets, an achievability result is obtained using constant-composition random coding, and by using a small fraction of the block to transmit the type of the state sequence. For error probabilities less than 1 2 , it is shown that the second-order...
متن کاملOn " Dirty-paper Coding "
regardless of what Q is. The title of Costa’s work came by making an analogy to the problem of writing on dirty paper, where the reader cannot nominally distinguish dirt from ink. There are many scenarios where this result may be applied. In the field of information hiding (or watermarking), a message is encoded in u, which is to be embedded in the host waveform i using the signal s. Data compr...
متن کاملon translation of phatic communion and socio-cultural relationships between the characters of the novels
phatic communion is a cultural concept which differs across cultures. according to hofstede (2001), the u.s. tends to have individualistic culture; however, asian countries tend to have collectivistic cultures. these cultures view phatic communion differently. in individualistic cultures like u.s., phatic communion reflects speakers’ socio-cultural relationships in conversations. to see whether...
15 صفحه اولThe Robustness of Dirty Paper Coding and The Binary Dirty Multiple Access Channel with Common Interference
A dirty-paper channel is considered, where the transmitter knows the interference sequence up to a constant multiplicative factor, known only to the receiver. Lower bounds on the achievable rate of communication are derived by proposing a coding scheme that partially compensates for the imprecise channel knowledge. We focus on a communication scenario where the signalto-noise ratio is high. Our...
متن کاملDirty-Paper Coding for the Multi-Access Channel with Conferencing
We derive the capacity region of the two-user dirtypaper Gaussian multi-access channel (MAC) with conferencing encoders. In this MAC, prior to each transmission block, the transmitters can hold a conference in which they can communicate with each other over error-free bit-pipes of given capacities. The received signal suffers not only from additive Gaussian noise but also from additive interfer...
