amplitude-modulation radio

基本解釋

The ultra wideband (UWB) radio models have been introduced with pulse-position-modulation (PPM), on-off-keying (OOK) and pulse-amplitude-modulation (PAM).
分析了超寬帶沖激無線電的脈位調(diào)制、通斷鍵控調(diào)制和脈沖幅度調(diào)制的信號模型。
From this point, M-ary Quadrature Amplitude Modulation (MQAM), MultiCarrier Modulation (MCM) and adaptive modulation techniques are good candidates in next generation mobile radio system.
從這一點(diǎn)出發(fā)，多元正交幅度調(diào)制（MQAM）、多載波調(diào)制（MCM）及自適應(yīng)調(diào)制技術(shù)成爲(wèi)下一代移動無線系統(tǒng)中最有競爭力的幾種候選技術(shù)。
