Kaedah penentuan had pelepasan telah dikaji dengan menggunakan taburan kebarangkalian amplitud (APD) untuk gangguan elektromagnet berdenyut berkemungkinan rendah akibat nyahcas. Ciri-ciri kaedah ini adalah 1) tanpa menggunakan hubungan yang dilaporkan sebelum ini antara APD dan kadar ralat bit, had diperoleh menggunakan impak terukur gangguan berdenyut pada pelbagai sistem komunikasi tanpa wayar yang mempunyai lebar jalur yang berbeza, dan 2) gangguan yang disebabkan oleh pelepasan dengan kebolehulangan yang lemah disimulasikan oleh gelombang sinus termodulat nadi yang kerap berulang untuk membolehkan penilaian yang stabil terhadap kualiti komunikasi. Had berasaskan APD ditentukan daripada kekerapan pengulangan nadi bagi gangguan simulasi supaya kadar ralat blok (BLER) adalah kurang daripada had tertentu dalam sistem wayarles yang paling sensitif kepada gangguan berdenyut. Dalam piawaian antarabangsa CISPR 32 yang mengawal gangguan elektromagnet, gangguan terpancar akibat nyahcas dikecualikan daripada penggunaan had pengesanan puncak kerana kebarangkalian kejadiannya yang rendah. Dalam makalah ini kita secara kuantitatif menentukan kriteria yang sesuai bagi kebarangkalian untuk pengecualian. Menggunakan kaedah tersebut, kami mengukur kesan gangguan denyutan berkemungkinan rendah pada sistem wayarles utama dan mendapati bahawa sistem GSM dan Wi-Fi adalah yang paling sensitif. Had berasaskan APD baharu diperoleh berdasarkan penemuan ini. Had berasaskan APD yang ditentukan oleh kaedah yang dicadangkan membolehkan penilaian yang sah bagi gangguan denyutan kebarangkalian kejadian rendah tanpa mengecualikan pengukuran tanpa syarat.

Abstract: A method of determining emission limits was studied by using the amplitude probability distribution (APD) for low-probability pulsed electromagnetic disturbances due to discharge. The features of this method are 1) without using the previously reported relationship between APD and bit error rate, the limits are derived using the measured impact of a pulsed disturbance on various wireless communication systems having different bandwidths, and 2) disturbances caused by discharge with poor reproducibility are simulated by regularly repeated pulse-modulated sine waves to enable stable evaluation of the communication quality. APD-based limits are determined from the pulse repetition frequency of the simulated disturbance such that the block error rate (BLER) is less than a certain limit in wireless systems that are most sensitive to the pulsed disturbance. In the international standard CISPR 32 regulating electromagnetic disturbance, radiated disturbance due to discharge is excluded from the application of peak detection limits because of its low occurrence probability. In this paper we quantitatively determine appropriate criteria of the probability for the exclusion. Using the method, we measured the impact of low-probability pulsed interference on major wireless systems and found that GSM and Wi-Fi systems were the most sensitive. New APD-based limits were derived on the basis of these findings. The APD-based limits determined by the proposed method enable a valid evaluation of low-occurrence-probability pulsed disturbances without unconditionally excluding the measurement.
