偽隨機噪聲
  • pseudo : adj. 〈口語〉假，偽，冒充的。
  • random : n 〈罕用語〉胡亂行為，偶然的[隨便的]行動[過程]。adj 1 任意的，胡亂的，隨便的；（話等）信口亂說的...

  • pn : 1. promissory note 【商業】本票，期票。2. please note 請注意。
  1. However, the traditional spreading codes are usually deterministic pseudo - noise ( pn ) codes, which can be duplicated, potentially compromising the transmission security. then the time varying and random spreading codes are expected

    為了提高擴頻通信系統的抗干擾性、降低信號被截獲的概率，我們希望擴頻碼是隨機的、動態變化的。
  2. Traditional spread spectrum communication adopts pseudo - noise ( pn ) codes as spreading codes. however, pn sequence is fixed and periodic, which threatens the transmission security. self - encoded spread spectrum ( sess ) employs random spreading sequences that are extracted from the random information data, abandoning the fixed sequence

    傳統的擴頻通信廣泛採用偽噪聲（ pseudo - noise ， pn ）序列作為擴頻序列， pn序列具有類噪聲特性，但它實際上是確定的周期序列，容易被復制。
