求翻譯:The amplitude and phase information of a set of received signal points is commonly represented graphically on a constellation diagram. Constellation diagrams are used for digitally modulation schemes where each transmitted symbol has a specific phase or amplitude value. These schemes range from BPSK to 768-QAM (V.34), 是什么意思?![]() ![]() The amplitude and phase information of a set of received signal points is commonly represented graphically on a constellation diagram.
