Error detector circuit for receiver operative to receive discretely-encoded signals

摘要

An error detector circuit, and an associated method, for a discrete receiver. The error detector circuit indicates bad frames of binary information signals which contain distorted bits of data in numbers so great as to prevent a convolutional decoder from generating, accurately, a decoded signal. When bit errors are detected in numbers beyond a first preselected value of the signal quality of a received signal combined with the detected number of bit errors forms a signal beyond a second preselected value, a bad frame is indicated.
