Abstract
An error detection system for a discrete receiver. The error detection system indicates bad frames of binary information signals which contain distorted bits in densities so great as to cause a convolutional decoder to generate an incorrect, decoded signal. A signal decoded by a convolutional decoder is re-encoded by an encoder, and the re-encoded signal is compared with the signal received by the receiver. When portions of the re-encoded signal differ too greatly from the actual, received signal, a bad frame indication is generated.
