This paper describes the design, testing, and measured performance of a rate 11/12 self‐orthogonal convolutional codec that meets the bit‐error‐rate objective of M‐state quadrature amplitude modulation systems in terrestrial radio transmission. The objective is to reduce a bit error probability of 10−6 to 10−10 or smaller. In fact, the measured output error probability is well below 10−10 when the channel error probability is below 10−5.
