中文摘要 | 在這篇論文中,我們應用了神經網路的頻譜估測,不僅能偵測頻譜的所在,同時 也能尋找這頻譜成份的強度。在我們提出的神經網路中,每一神經細胞代表一個頻譜成份 ( 頻率檢測 )。應用臨界效應和飽和效應配合神經細胞的解析度限制特性來估算頻率 (振幅檢 測 ) 的強度。在此篇論文中我們用 MATLAB 以 50 個神經細胞來模擬此神經網路。 我們分 別是依據樣本數和遞迴數來做類神經網路在系統容量上的模擬研究。 在樣本數大於 200 或 遞迴數大於 100 的情況下以 100 個神經細胞模擬結果顯示系統容量的最大值是 25。 |
英文摘要 | In this paper, we use a neural network for the spectrum estimation which not only detects a location of the frequency component but also finds the intensity of the frequency. In our proposed neural network, each neuron represents one frequency component (frequency detection). The threshold and saturation effects of the neuron together with the resolution limitation can be used for the estimation of the intensity of this frequency (amplitude detection). In this paper, we use MATLAB for the simulation of the neural network with 50 neurons. We study the total capacity of the neural network based on two parameters of sample number and iteration number. The simulation results have shown that the total capacity will reach a maxmum value of 25 neurons under the condition that the sample number and iteration number are greater than 200 and 100, respectively, for the system with 100 neurons. These are the threshold and saturation effects in the neural network. |
