In analog input channel, the combination software filter is applied to obtain more credible data as possible, and median voting circuit module is adopted in output channel to gain accurate outputs
在模擬輸入通道中採用中位值濾波和遞推平均濾波的組合演算法，來獲取盡可能可靠的輸入數據，在模擬輸出通道中則採用中值表決電路通用模塊實現正確的模擬輸出。 -
Because of the affection of noise and signal fading, in order to high data rate access and high quality, wireless communication need new technology to improve the link reliability and enhance the spectrum efficiency. mimo ( multiple input and multiple output ) can enhance the spectrum efficiency and increase channel capacity greatly, and reduce the multipath affection without spectrum band and power increasing. the 3th generation mobile communication wcdma is coming, with the purpose of putting mimo, stbc ( space time block coding ), space diversity into practice of wcdma systems, in order to lay the foundation of 3g toward 4g, this dissertation has done some research under this background
在發射機和接收機使用多個天線進行數據傳輸的多輸入多輸出（ mimo ）技術，可以在不增加帶寬和天線發送功率的條件下，成倍的提高頻譜利用率，提高系統的通道容量，還可以抗多徑干擾。第三代移動通信wcdma即將到來，為了將多天線技術（ mimo ） ，空間分集技術，空時編碼技術用到wcdma系統中去，為第三代移動通信向第四代移動通信系統平穩過渡奠定一定的基礎，需要做一些理論上的研究。 -
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。
