6. since the monitor precision of quasi - dynamic calibration system is very important, the model of the four channel electric pressure - measuring system in frequency domain is built up. the cause of variance is analyzed. the error function of the system is defined and the formula of correcting the system error is derived
6由於落錘液壓動標裝置校準系統的校準壓力監測精度極為重要，本文對四路電測壓力系統進行頻域建模，分析了產生不一致的原因，定義了系統的誤差函數及推導了統一誤差模型的修正公式。 -
Mtcem ( multi - tone envelope method ) can accurately forecast performance parameters on a set of stored channel and directly decide usable frequency choice. as hf channel characteristic is closed to gauss, mtcem may be simplified to multi - tone envelope method rtce system. for certain user ' s request and link status, double tone complex envelope method rtce, double tone envelope rtce, adaptive hf channel sounding and communication system, all that can easily derived from mtcem
多音復包絡實時選頻系統，當通道特性近似於高斯通道時，整個系統可以簡化為多音包絡法實時選頻系統，針對不同的用戶要求和電路通道狀況，很容易由它派生出較為簡單的系統，如雙音復包絡法實時選頻系統，雙音包絡法實時選頻系統，短波自適應通道探測和通信系統。 -
So far, there is not much research on the signal detection of da - mimo system, and the general frequency selective channel is not taken into consideration. in chapter 3 of this dissertation, the coherent signal detection algorithms for da - mimo system under both flat fading and frequency selective fading channels are derived. and the analysis of the factors which affect the performance of the detection algorithms is also illustrated through computer simulations
針對分佈mimo信號檢測目前研究較少，並且沒有考慮一般意義下的頻率選擇性通道的情況，本文在第三章分別推導了基於平坦衰落和頻率選擇性衰落通道環境的分佈mimo信號相干檢測演算法，並通過計算機模擬，對影響演算法檢測性能的因素進行了分析討論。
