The performance of a simulated convolutional decoder on measured HF and tropospheric data channels (Corresp.)

A Massey diffuse convolutional decoder was simulated in the IBM computer and used to decode binary digital error patterns measured at bits/s on an HF radio circuit and on a multiple link data circuit dominated by a tropospheric scatter path. It was found that the simulation performed at least as well as previous cyclic code simulations on HF radio and better than cyclic codes on the tropospheric path.
