Abstract
"RECEPTOR DE SINAL DE TELEVISãO DIGITAL". Resultados de decodificação de símbolos obtidos usando filtragem de crista para suprimir artefatos de interferência de co-canal NTSC antes da decodificação de símbolos e resultados de decodificação de símbolo obtidos sem usar tal filtragem de crista, antes da decodificação de símbolo são comparados para determinar quais resultados de decodificação de símbolo devem ser selacionados como resultados de decodificação de símbolo final. Os resultados de decodificação de sím bolo obtidos usando filtragem de crista para suprimir artefatos de interferência de co-canal NTSC são selacionados como resultados de decodificação de símbolo final quando a interferência de co-canal NTSC ocorre. Os sinais de televisão digital são detectados para determinar quando se obtém a interportadora NTSC de 4,5 MHz, no sentido de confirmar a ocorrência de interferência de co-canal NTSC substancial."DIGITAL TELEVISION SIGNAL RECEIVER". Symbol decoding results obtained using crest filtering to suppress NTSC co-channel interference artifacts before symbol decoding and symbol decoding results obtained without using such crest filtering, before symbol decoding are compared to determine which results symbol decoding should be selected as the final symbol decoding results. The results of symbol decoding obtained using crest filtering to suppress NTSC co-channel interference artifacts are selected as final symbol decoding results when NTSC co-channel interference occurs. Digital television signals are detected to determine when to obtain the 4.5 MHz NTSC carrier, in order to confirm the occurrence of substantial NTSC co-channel interference.
