在無線感測、車用無線隨意網路以及感知無線電網路中,採用通道跳頻碼在無線網路動態多存取系統中是近日熱門的研究議題。在本論文中,我們設計了應用於感知無線電環境中的同步對稱通道跳頻碼。此通道跳頻碼滿足碼之通道交會,通道平均使用及頻道交會使用率的特性。除了設計通道跳頻碼之外,我們也分析了新提出之通道跳頻碼在基於不同之封包碰撞迴避機制下,兩種不同傳輸環境之通道跳頻碼的封包交換利用率。我們的研究結果顯示,新提出之通道跳頻碼擁有比現今其它同步通道跳頻碼較短之跳頻碼周期及通訊交會延遲,因此能在感知無線電環境下達到更頻繁之通訊交會比率及較大的封包交換利率。
Channel-hopping (CH) sequences have recently been studied for dynamic multiple-access mobile applications, such as wireless sensor, vehicular ad hoc network and cognitive radio (CR) network. In this thesis, a new family of synchronous-symmetric CH sequences over Galois extension field is constructed. They satisfy the channel-overlap, even-channel-use, and full channel utilization design criteria. Besides designing CH sequences, their operations in two transmission scenarios involving different collision-avoidance mechanisms are also analyzed and compared in terms of rendezvous-success (RS) rate. Our study shows that the new sequences have shorter period and maximum time to rendezvous, thus supporting more frequent rendezvous and higher rate in CR networks.
