摘要: 
除了設計通道跳頻碼之外,在感知無線電網路中找到良好的通訊交會方法以改善頻譜使用效率與分散通道負載也是一重要考量。由於次要用戶不能在主要用戶使用通道時進行傳輸,因此我們利用通道替換機制將被占用通道替換成可用通道。在本論文中,我們提出了應用於感知無線電環境中新的通道替換方法,並檢驗該方法之通道再次重疊、可用通道平均使用以及可用通道使用率之特性。與先前提出之通道替換演算法相比,新建構之通道替換演算法在擁有較佳的系統效能,並提供感知無線電網路穩定的交會過程。

Besides designing channel-hopping (CH) sequences with desirable characteristics, finding good methods of communication rendezvous is important for improving spectral efficiency and alleviating traffic load of cognitive radio (CR) networks. As secondary users cannot transmit in channels occupied by primary (licensed) users, some sort of channel-replacement methods to replace unavailable channels in CH sequences are needed. In this paper, a new channel-replacement method, which can maintain the channel-overlap, even-channel-use, and full-channel-use properties of the original CH sequences, is proposed and analyzed. Compared with previous works, the proposed channel-replacement method is better in various aspects, such as even-available-channel-use, channel diversity, and time-to-rendezvous, and can maintain a stable and uniform rendezvous process in the CR networks.
