Variable-length 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 a noisy feedback link. We demonstrate that the Burnashev upper bound on the reliability function is achievable given any noisy feedback channel, as long as the desired rate of communication is close enough to capacity. We also demonstrate that Fo...
متن کاملExponential bounds on error probability with Feedback
Feedback is useful in memoryless channels for decreasing complexity and increasing reliability; the capacity of the memoryless channels, however, can not be increased by feedback. For fixed length block codes even the decay rate of error probability with block length does not increase with feedback for most channel models. Consequently for making the physical layer more reliable for higher laye...
متن کاملOn the error exponent of variable-length block-coding schemes over finite-state Markov channels with feedback
The error exponent of Markov channels with feedback is studied in the variablelength block-coding setting. Burnashev’s [5] classic result is extended and a single letter characterization for the reliability function of finite-state Markov channels is presented, under the assumption that the channel state is causally observed both at the transmitter and at the receiver side. Tools from stochasti...
متن کاملMultipath Communication with Finite Sliding Window Network Coding for Ultra-Reliability and Low Latency
We use random linear network coding (RLNC) based scheme for multipath communication in the presence of lossy links with different delay characteristics to obtain ultra-reliability and low latency. A sliding window version of RLNC is proposed where the coded packets are generated using packets in a window size and are inserted among systematic packets in different paths. The packets are schedule...
متن کاملFast Iterative Coding Techniques for Feedback Channels
A class of capacity-achieving, low-complexity, highreliability, variable-rate coding schemes is developed for communication over discrete memoryless channels with noiseless feedback. Algorithms for encoding and decoding that require computations growing linearly with the number of channel inputs used are developed. The error exponent associated with the scheme is shown to be optimal and implies...
