Abstract: An error detection system for a discrete receiver. Sequences of bits together forming frames of information comprise the signal received by the discrete receiver. The signal is decoded by a convolutional decoder and is re-encoded by an encoder. Successive portions of nonoverlapping sets of adjacently positioned bits of the re-encoded signal formed by the encoder are compared with corresponding bits of a signal representative of the signal received by the receiver. When excessive numbers of the successive portions of the signals which are compared include bit dissimilarities, a bad frame indication is generated.

Abstract: An apparatus, and associated method, for determining signal transmission quality levels of a discretely-encoded information signal received by a receiver. The signal strength of the received signal is calculated, and the levels of interference introduced upon the information signal is determined. The value of the signal strength is weighted by the amount of interference introduced upon the information signal. The resultant weighted signal forms the signal transmission quality level. The value of the signal transmission quality level is displayed to provide a user with a quantitative indication of the signal transmission quality level of the signal received by the receiver.

Abstract: An error detection system for discrete receiver. The error detection system indi cates bad frames of binary information signal which contain distorted bits in excessive numbers so great as to cause a convolutional decoder to generate an incorrect, decoded signal. A signal decoded by a convolutional decoder (512) is re-encoded by an encoder (524), and the re-encoded signal (530) is compared with the signal received (506) by the receiver. When excessive numbers of re-encoded signal portions differ too greatly with corresponding portions of an actual, received signal, a bad frame i ndication is generated (590).
