Selection of a forward error correcting code for the data communication radio link of the Advanced Train Control System

A method for selecting a forward error correcting (FEC) code for the Advanced Train Control System (ATCS) radio data link is described. The application of the ATCS and the performance issues involved in selecting a code are detailed. On the basis of the data, the ATCS Communications Component Specification Drafting Committee chose the Reed-Solomon 2 code as the FEC code for ATCS. This choice was based on best overall performance in providing throughput and good performance relative to other codes on other metrics.<
