  5. There is less wireless interference in lfmcw signal, because the structure of transmitting and receiving devices is simpler, and the transmitted spectrum is narrower

    Lfmcw信號發射和接收設備簡單，發射頻譜窄，使得無線電干擾問題較少。
  6. Combined with the actual example in one power plant, many analyses, such as water quality analysis, ignition analysis, plasma transmitted spectrum, and scanning electron microscopy etc., have been carried out, to analyse the quality of cooling water, and properties in aspects of fouling, silt, and microorganism respectively

    結合某廠實例，採用水質分析、灼燒分析、等離子體發射光譜、掃描電子顯微鏡等分析手段分別對冷卻水水質、污垢、淤泥、微生物等的特性進行了分析。
  7. Future mobile communications have to support the transmission of high rate data and multimedia applications in the radio spectrum, which is already extremely scarce. the basic idea of adaptive coded modulation is to maintain a constant throughput by varying the transmitted power level, symbol transmission rate, constellation size, coding rate or any combination of these parameters. thus, without sacrificing bit - error rate ( ber ), these schemes provide high average spectral efficiency by transmitting at high speeds under favorable channel conditions, and reducing throughput as the channel degrades

    自適應編碼調制（ adaptivecodedmodulation ， acm ）的基本思想是在不犧牲系統傳輸性能（比如ber ）為代價的前提下，通過單獨改變發送功率、波特率、編碼方案、碼率、調制方式，或者是綜合改變前面所述的各種參數，在有利的通道條件下，獲得較大的吞吐量，當通道質量下將時，相應地降低傳輸速率，最終達到提高平均頻譜效率的目的。
  8. The drfm can store a transmitted signal of the radar and replicate it on command. properly implemented, in addition to radar signals, the drfm can generate noise jamming and other electromagnetic signals typically experienced in the ew environment. other difficult to generate deception spectrums can be easily implemented by analysis of the desired spectrum
