Abstract: An error detection system for discrete receiver. The error detection system indicates 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 indication is generated (590).

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 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.

Abstract: SISTEMA DE DETECCION DE ERRORES EN LA RECEPCION DE SEÑALES CODIFICADAS TRANSMITIDAS POR RADIOFRECUENCIA, QUE INDICA BLOQUES ERRONEOS DE SEÑALES BINARIAS DE INFORMACION QUE CONTIENEN BITS DEFORMADOS EN DENSIDADES TAN GRANDES QUE HACEN QUE UN DECODIFICADOR CONVOLUCIONAL GENERE UNA SEÑAL DECODIFICADA, INCORRECTA. UNA SEÑAL DECODIFICADA POR UN DECODIFICADOR CONVOLUCIONAL SE RECODIFICA MEDIANTE UN CODIFICADOR Y LA SEÑAL RECODIFICADA SE COMPARA CON LA SEÑAL RECIBIDA POR EL RECEPTOR. CUANDO PORCIONES DE LA SEÑAL RECODIFICADA DIFIEREN DEMASIADO DE LA SEÑAL REAL RECIBIDA SE GENERA UNA INDICACION DE BLOQUE ERRONEO.

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.
