Gaussian Z Channel with Intersymbol Interference
In this paper, we derive a capacity inner bound for a synchronous Gaussian Z channel with intersymbol interference (ISI) under input power constraints. This is done by converting the original channel model into an n-block memoryless circular Gaussian Z channel (n-CGZC) and successively decomposing the n-block memoryless channel into a series of independent parallel channels in the frequency dom...
متن کاملVariable-length channel coding with noisy feedback
It is known that perfect noiseless feedback can be used to improve the reliability of communication systems. We show how to make those gains robust to noise on the feedback link. We focus on feedback links that are themselves discrete memoryless channels. We demonstrate that Forney’s erasure-decoding exponent is achievable given any positive-capacity feedback channel. We also demonstrate that a...
متن کاملJoint source-channel coding with feedback (extended)
This paper quantifies the fundamental limits of variable-length transmission of a general (possibly analog) source over a memoryless channel with noiseless feedback, under a distortion constraint. We consider excess distortion, average distortion and guaranteed distortion (d-semifaithful codes). In contrast to the asymptotic fundamental limit, a general conclusion is that allowing variable-leng...
متن کامل8. Transmission of a Gaussian Signal through a Channel with Noiseless Feedback. Optimal Coding and Decoding
We consider X as a signal which has to be transmitted through a noise channel. Assume also that the exit (Yt)t≥0 of the noisy channel is observable. Three parameters: the time t, the signal X, and the observation Y t 0 might me used for creating of a code A(t,X, Y t 0 ) for X. In other words, at the time t, instead of X, we transmit a new signal A(t,X, Y t 0 ) generated by t, X, and observation...
متن کاملOn Using Feedback in a Gaussian Channel
For information transmission a discrete time channel with independent additive Gaussian noise is used. There is also another channel with independent additive Gaussian noise (the feedback channel), and the transmitter observes without delay all outputs of the forward channel via that channel. Transmission of nonexponential number of messages is considered (i.e. transmission rate equals zero) an...
