技術說明

本發明揭示一個建構於適應性網路模糊推論系統(adaptive network-based fuzzy inference system, ANFIS)之三層串接式認知引擎(cognitive engine) 方法及裝置，使認知無線電(cognitive radio, CR)行動通訊網路可以因應網路環境之變化，彈性、可靠而有效率的使用無線行動通訊網路之頻譜與功率資源之智慧型網路資源分配控制器，包含第一層之ANFIS資料率控制器(ANFIS rate controller, ARC)、第二層之ANFIS功率控制器(ANFIS power controller, APC)與第三層之ANFIS干擾控制器(ANFIS interference controller, AIC) ，可偵測網路話務性能、傳接機性能、用戶車速、通道環境變化、傳接機訊干雜比，訓練ANFIS控制器參數，分別適應性控制傳接機的資料率、發射功率與天線零點數目之指配，使認知無線電行動通訊網路的用戶可產生最佳化之最大系統平均通達率、最小發射功率與干擾的多媒體通訊網路服務品質(quality of service, QoS)。 A three layer cascade adaptive neural fuzzy inference system (ANFIS) based intelligent controller is proposed for the mobile wireless network to optimize the maximum average throughput, minimum transmit power and interference for multimedia call services. It can always guarantee the quality of service (QoS) that remains the new call blocking probability and handoff failure probability lower than 0.05, and maintain the acceptable bit error rate (BER) of the receiver in mobile wireless network. The proposed intelligent controller is designed with a three layer cascade architecture, which mainly contains an ANFIS rate controller (ARC) in the first layer, an ANFIS power controller (APC) in the second layer and an ANFIS interference controller (AIC) in the third layer. If the interference is too large to achieve the required SINR of the receiver, the AIC is initiated to adjust the number of antenna nulls to reduce the interference power automatically.
