描述

AAZSZSZ每個部件都有會降低系統(tǒng)整體功能的不理想性能。降低系統(tǒng)整體性能的最主要、最基本原因是熱噪聲?？梢酝ㄟ^載波功率來設置信道內(nèi)的載噪比(CNR)或者信噪比(SNR)。在特定的信噪比和帶寬情況下，可通過香農(nóng)定律來定義每秒鐘的最大信道容量(位數(shù))，但在實際操作中永遠不會達到這個最大值。為確保最佳系統(tǒng)設計，必須準確模擬信道內(nèi)所有真實存在的壞損。

仿真測試解決方案

全面、真實的通信通道仿真是設計和驗證的需要。針對衛(wèi)星通信業(yè)務發(fā)展的需要，設計人員需要更為有效的仿真測試設備，要求它具有寬帶仿真和測試功能，真實地模擬通道中環(huán)境壞損因素、以及通道中各部件對系統(tǒng)的影響。這樣，設計人員才能在設計階段有效地控制設計余度，同時滿足成本、可靠性和容量的要求。

目前，衛(wèi)星系統(tǒng)設計者在設計過程中可以使用若干種輔助工具。設計模擬和測試工具主要有以下三種：計算機建模和模擬工具、制造和發(fā)射試驗衛(wèi)星、衛(wèi)星通道模擬器。

借助計算機建模和模擬工具，設計者可以建立多種信道壞損的模型，并通過模型綜合考慮系統(tǒng)的總體性能。這些工具能夠完成基本設計，并進行性能評估。此類軟件用于臺式機和高級工作站。為得到準確的結果，即使使用最快的處理器也需要花費大量的計算時間，這樣就限制了模擬對象的數(shù)量，也限制了能夠分析的綜合壞損模型。這些模型也可能并沒有正確反映實際情況。
