On Doubly-Cyclic Convolutional Codes
Cyclicity of a convolutional code (CC) is relying on a nontrivial automorphism of the algebra F[x]/(xn - 1), where F is a finite field. A particular choice of the data leads to th...

Multi-user OFDM Based on Braided Convolutional Codes
Abstract Braided convolutional codes (BCCs) form a class of iteratively decodable convolutional codes that are constructed from component convolutional codes. In braided code divis...

On efficient soft-input soft-output encoding of convolutional codes
We study efficient algorithms for soft-input soft-output (SISO) encoding of convolutional codes. While the BCJR algorithm has been suggested for SISO encoding, we show that a for...

Hybrid ARQ Scheme Based on Recursive Convolutional Codes and Turbo Decoding
Abstract— We propose a hybrid ARQ scheme using recursive convolutional codes and the turbo principle. In the first transmission the system encodes the data through a systematic ...
