Akses spektrum dinamik (DSA) mengeksploitasi sumber frekuensi kosong melalui akses wayarles teragih. Kedua-dua nod DSA, tuan dan hamba, mengakses saluran yang berbeza, dan dengan itu, tidak boleh berkomunikasi antara satu sama lain. Untuk mengimbangi ketidakpadanan saluran akses antara kedua-dua nod, saluran pertemuan, yang menukar isyarat kawalan antara dua nod, telah dipertimbangkan. Saluran pertemuan berdasarkan nisbah penghunian saluran (COR) secara adaptif membina saluran mengikut penghunian saluran sistem lain, dan kedua-dua saluran pertemuan berkelajuan tinggi dan kecekapan penggunaan tinggi sumber frekuensi dicapai disebabkan oleh eksploitasi kekosongan saluran. Dalam saluran pertemuan berdasarkan COR, tuan dan hamba mengenali saluran dengan COR terukur minimum sebagai saluran unggul. Apabila tuan menghantar isyarat kawalan melalui saluran unggul yang diiktiraf oleh tuan, hamba mengakses saluran unggul yang diiktiraf oleh hamba dengan kadar akses yang lebih tinggi daripada saluran lain. Akibatnya, hamba boleh menerima isyarat kawalan dengan kebarangkalian tinggi dan dengan itu saluran pertemuan berkelajuan tinggi dicapai. Jika tuan dan hamba mengenali saluran yang berbeza sebagai saluran unggul, kadar akses ke saluran lain harus lebih besar. Ini kerana hamba mendapat peluang untuk menerima isyarat kawalan melalui saluran yang berbeza daripada saluran unggul yang diiktiraf oleh hamba dan dengan itu kebarangkalian yang tinggi bahawa hamba boleh menerima isyarat kawalan dikekalkan. Oleh itu, kadar akses hamba harus dibina mengikut pengiktirafan saluran unggul oleh tuan dan hamba. Dalam makalah ini, kadar capaian hamba kepada saluran unggul dibina secara optimum menggunakan kebarangkalian dianalisis untuk menyiapkan saluran pertemuan. Analisis kebarangkalian penyiapan saluran pertemuan termasuk pengiktirafan saluran unggul oleh tuan dan hamba. Walaupun tuan dan hamba mengenali saluran yang berbeza, kadar akses hamba yang dibina boleh mengekalkan saluran pertemuan berkelajuan tinggi. Daripada analisis teori dan simulasi komputer, saluran pertemuan berdasarkan COR dengan kadar capaian optimum ke saluran dengan COR terendah mencapai masa yang dikurangkan untuk saluran pertemuan.

Abstract: Dynamic spectrum access (DSA) exploits vacant frequency resources via distributed wireless access. The two nodes of DSA, master and slave, access different channels, and thus, cannot communicate with each other. To compensate for the access channel mismatch between the two nodes, a rendezvous channel, which exchanges control signals between two nodes, has been considered. The rendezvous channel based on channel-occupancy ratio (COR) adaptively constructs the channel in accordance with the channel occupancy of other systems, and both a high-speed rendezvous channel and high usage efficiency of the frequency resource are accomplished owing to exploitation of the vacant channel. In the rendezvous channel based on COR, the master and slave recognize the channel with minimum measured COR as the superior channel. As the master sends the control signals through the superior channel recognized by the master, the slave accesses to the superior channel recognized by the slave with higher access rate than to the other channels. As a result, the slave can receive the control signals with highly probability and thus high speed rendezvous channel is achieved. If the master and the slave recognize the different channel as the superior channel, the access rate to the other channel should be larger. This is because the slave obtains the opportunity of receiving the control signals through the different channel from the superior channel recognized by slave and thus the high probability that the slave can receive the control signals is maintained. Therefore, the access rate of slave should be constructed in accordance with the recognition of superior channel by master and slave. In this paper, the access rate of slave to the superior channel is optimally constructed using the analyzed probability of completion of rendezvous channel. The analysis of the probability of completion of rendezvous channel includes the recognition of superior channel by master and slave. Even if the master and the slave recognize the different channel, the constructed access rate of slave can maintain the high speed rendezvous channel. From the theoretical analysis and computer simulation, the rendezvous channel based on COR with the optimal access rate to the channel with the lowest COR achieves reduced time for the rendezvous channel.
