    利用擴頻通信原理，分析擴頻通信的抗干擾特性，在此基礎上，闡述了電力線載波通信系統的基本結構，提出了一種利用軟體編程實現電力線載波擴頻通信的方法。該方法不增加硬體成本，即能達到提高通信質量、降低誤碼率的目的。
  3. Frequency source is widely used in today ' s electronic equipment and even refered as " a heart " of many electronic systems. the frequency synthesizer with a lot of channels and high frequency stability by means of theory of phase locking has almost been a necessary component in the modern electronic systems such as telecommunication, radar and electronic countermeasure. the phase - locked frequency synthesizer can be generally divided into two kinds : one is digital phase locked frequency synthesizer, the other is analog sampling phase locked frequency synthesizer. compared with the prior, the latter has many merits such as lower phase noise, samller volume, lighter weight and lower power consumption and has a wide foreground in the equipments of microwave band

    利用鎖相原理來獲得波道數目眾多、頻率穩定度很高的頻率合成器，幾乎已成為現代通信、雷達和電子對抗等電子系統不可缺少的組成部分。鎖相式頻率合成器一般分為數字鎖相頻率合成器和模擬取樣鎖相頻率合成器兩類。取樣鎖相頻率合成器與數字鎖相頻率合成器相比，具有相位噪聲低、體積小、重量輕和功耗低等優點，尤其在微波波段的電子設備中，具有廣闊的應用前景。
