WebBCH convolutional code as a standard rate-k=n (k < n) convolutional code designed using ideas from BCH theory. We focus on binary BCH codes, but the approach general-izes to non-binary BCH codes such as Reed-Solomon codes. Although we refer to the convolutional code as having rate one, the rate is, of course, actually below one because of
