Error rate monitoring for digital communications
Abstract
Four classifications of error monitoring for digital communications are presented. The first method uses test sequences, allowing transmitted and received signals to be compared, and degradation introduced into the system to be assessed. This system provides very accurate information over a specific time period. Signal parameters can also be used for error monitoring, providing a more qualitative measurement than the other methods. The format violation method is slow but provides relatively precise quantitative measurements. Pseudo-error monitoring also gives numerical results, but is faster and less precise than the format violation method. Particular uses for each system are given: test sequences are used when communication system characteristics are unknown, parameter measurements are made when there is a suspected problem, and format violation and pseudo-error monitoring must be built into the communication system. The use of microcomputers for information processing is foreseen, resulting in more detailed and accurate error monitors.
