アナログスクランブル信号と64QAM信号の隣接伝送時における干渉妨害の検討 : 予備実験とその考察

概要

論文の詳細を見る
Mutual interference between an analog sync pulse compression (scrambled) signal an adjacent 64QAM signal was described. In case that the analog signal level was larger, more than 5dB, than the 64QAM signal level, an upper adjacent 64QAM signal was degraded in BER by a key signal which is multiplexed with a sound carrier of the analog signal. Regenerated key signal for lower adjacent analog scrambled signal was errored or increased litter by the 64QAM signal. Whose level was larger than the analog signal level.
