Variable-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 کاملVariable-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 کاملVariable-length codes for channels with memory and feedback: error-exponent upper bounds
The reliability function of memoryless channels with noiseless feedback and variable-length coding has been found to be a linear function of the average rate in the classic work of Burnashev. In this work we consider unifilar channels with noiseless feedback and study upper bounds for the channel reliability function with variable length codes. In unifilar channels the channel state is known to...
متن کاملError-Free Communication Over State-Dependent Channels with Variable-Length Feedback
The zero-error capacity of state-dependent channels with noiseless feedback is determined, under the assumption that the transmitter and the receiver are allowed to use variable-length coding schemes. Various cases are analyzed, with the employed coding schemes having either bounded or unbounded codeword lengths and with state information revealed to the encoder and/or decoder in a strictly cau...
