Variable-length Convolutional Coding for Short Blocklengths with Decision Feedback
Adam R. Williamson, Tsung-Yi Chen, Richard D. Wesel
This paper presents a variable-length decision-feedback scheme that uses tail-biting convolutional codes and the tail-biting Reliability-Output Viterbi Algoritm (ROVA). Comparing w…
Increasing Flash Memory Lifetime by Dynamic Voltage Allocation for Constant Mutual Information
Tsung-Yi Chen, Adam R. Williamson, Richard D. Wesel
The read channel in Flash memory systems degrades over time because the Fowler-Nordheim tunneling used to apply charge to the floating gate eventually compromises the integrity of…
Reliability-output Decoding of Tail-biting Convolutional Codes
Adam R. Williamson, Matthew J. Marshall, Richard D. Wesel
We present extensions to Raghavan and Baum's reliability-output Viterbi algorithm (ROVA) to accommodate tail-biting convolutional codes. These tail-biting reliability-output algori…
Feedback Communication Systems with Limitations on Incremental Redundancy
Tsung-Yi Chen, Adam R. Williamson, Nambi Seshadri +1
This paper explores feedback systems using incremental redundancy (IR) with noiseless transmitter confirmation (NTC). For IR-NTC systems based on {\em finite-length} codes (with bl…
Reliability-based Error Detection for Feedback Communication with Low Latency
Adam R. Williamson, Tsung-Yi Chen, Richard D. Wesel
This paper presents a reliability-based decoding scheme for variable-length coding with feedback and demonstrates via simulation that it can achieve higher rates than Polyanskiy et…
Variable-Length Coding with Feedback: Finite-Length Codewords and Periodic Decoding
Tsung-Yi Chen, Adam R. Williamson, Richard D. Wesel
Theoretical analysis has long indicated that feedback improves the error exponent but not the capacity of single-user memoryless channels. Recently Polyanskiy et al. studied the be…
A Rate-Compatible Sphere-Packing Analysis of Feedback Coding with Limited Retransmissions
Adam R. Williamson, Tsung-Yi Chen, Richard D. Wesel
Recent work by Polyanskiy et al. and Chen et al. has excited new interest in using feedback to approach capacity with low latency. Polyanskiy showed that feedback identifying the f…
