A STudy of Convolutional Coding for High Frequency Data Transmission.

摘要

An introduction to convolutional coding is given and the process of threshold decoding is illustrated. The error characteristics of the HF channnel are briefly discussed and several coding methods are described. Particular attention is paid to families of diffuse and interleaved rate 2/3 codes and the results of computer simulations are presented. The comparative advantages of block coding and convolutional coding are described. (Author)
