Channel simulation and coding with side information
We study the minimum random bit rate required to simulate a random system (channel), where the simulator operates with a given external input. As measures of simulation accuracy we use both the variational distance and the d distance between joint input-output distributions. We find the asymptotic number of random bits per input sample required for accurate simulation, as a function of the dist...
متن کاملSecure Joint Source-Channel Coding With Side Information
The problem of transmitting an i.i.d Gaussian source over an i.i.d Gaussian wiretap channel with an i.i.d Gaussian side information is considered. The intended receiver is assumed to have a certain minimum SNR and the eavesdropper is assumed to have a strictly lower SNR compared to the intended receiver. The objective is minimizing the distortion of source reconstruction at the intended receive...
متن کاملIndex coding with side information
The Index Coding problem has attracted a considerable amount of attention in the recent years. The problem is motivated by several applications in wireless networking and distributed computing. An instance of the index coding problem includes a sender that holds an input x = (x1, x2, . . . , xn) ∈ {0, 1} and communicates with n receivers R1, . . . , Rn using wireless broadcast channel. Each rec...
متن کاملZero-Error Source-Channel Coding With Side Information
We consider coding for transmission of a source through a channel without error when the receiver has side information about the source. We show that separate source and channel coding is asymptotically suboptimal in general. By contrast, in the case of vanishingly small probability of error, separate source and channel coding is known to be asymptotically optimal. For the zero-error case, we s...
متن کاملChannel capacity and error exponents of variable rate adaptive channel coding for Rayleigh fading channels
We have evaluated the information theoretical performance of variable rate adaptive channel coding for Rayleigh fading channels. The channel states are detected at the receiver and fed back to the transmitter by means of a noiseless feedback link. Based on the channel state informations, the transmitter can adjust the channel coding scheme accordingly. Coherent channel and arbitrary channel sym...
