channel-data check 中文意思是什麼
channel-data check
解釋
通道數據檢查-
For data integrity, it exists in two problems, external interference and collisions that multi - tags occupying a single channel and transmitting their data lead into at the same time. we use data check and anti - collision algorithms to resolve those two problems respectively
本文分別對這兩個方面進行了研究,針對數據傳輸的完整性,主要存在兩個方面的問題,外界的干擾和多個應答器同時佔用通道發送數據發生沖突以致碰撞,運用數據校驗和防碰撞演算法分別解決這兩個問題。 -
In next mobile communication system to suffice more and more high - speed data service and demand of qos ( quality of service ) many new wireless link layer transport technologies are going to be used such as mimo ( multiple input multiple output ), ofdm ( orthogonal frequency division multiplexing ), channel coding and acm ( adaptive coding modulation ) etc. low density parity check ( ldpc ) codes were first discovered in 1960 ’ s which belong to linear block codes with their parity matrix being sparse
下一代移動通信系統為了滿足移動用戶對高速、寬帶數據傳輸業務不斷增長和更高服務質量的要求,採用了許多新的無線鏈路傳輸技術,包括多天線發射和接收技術、正交頻分復用技術、通道糾錯編碼技術和自適應編碼調制技術等。上世紀60年代提出的低密度校驗碼,是一種校驗矩陣為稀疏矩陣的線性分組碼。
