Through the reaserch of the paper, a satellite transmission and television signal incepting system using stabilization platform which is used on the moving carrier ( vehicle, boat, ship etc ) has been designed. it uses an embedded system which is based on arm7tdmi core microcontroller and c / os - ii real - time operating system to control and scout the movement of the antenna stabilization platform, can realize the real - timable and reasonable stance control of the antenna, and then can realize the real - time communications and the signal receiving between the satellite and the moving carrier
3 .通過論文的研究，開發出了一種用於移動載體（車、船、艦等）上利用穩定平臺來進行衛星通信與電視信號接收的系統? ? 「動中通」移動載體衛星通信與電視接收系統。該系統採用基於arm7tdmi核微控制器和c / os - ii實時操作系統的嵌入式系統來控制天線穩定平臺的運動，可以實現對天線實時而合理的姿態控制，從而實現移動載體與衛星之間的實時通信和信號接收。 -
36 covers the fundamentals of digital communications and networking, including the basics of information theory, sampling and quantization, coding, modulation, signal detection and system performance in the presence of noise
36包含數位通訊和網路基礎，其中計有基本的資訊理論、取樣及量化、編碼、調變、訊號偵測及有雜訊時的系統效能。 -
Multi - uesr detection ( mud ) refers to signal detection in multiple access communications. this detection has many good properties, such as decreasing multiple access interference, canceling out or moderating near - far resistance, able to decrease the requirement for output control, compensating the effects due to inoptimal orthogonality, improving system performance and increasing system capacity. mud is one of the methods that can overcome the mai in cdma with most potential and complete and becomes one of the critical techniques in the third generation mobile communication
多用戶檢測是指多址通信中的信號檢測，具有抑止多址干擾;消除或減輕遠近效應;可適當降低對功率控制的要求;彌補擴頻碼互相關性不理想造成的影響;改善系統性能，提高系統容量等眾多優點，是克服cdma多址干擾最有潛力、最徹底的一種方法，並已成為第三代移動通信標準中倡導的關鍵技術之一。 -
Also in this part, multi - thread programming and network communications are presented. in the visual system one thread process receives the control signal and the other take charge of the refreshing window. this technique solves the delay phenomenon between the visual system and the operations on the control panel
最後論文中對多線程編程進行了詳細分析，針對實時視景模擬系統的特點，使用一個線程完成控制信號的接收工作，另一個線程負責整個場景畫面的繪制工作。 -
In general, fpga is mostly used in high - speed communications systems or high - speed signal processing systems because of its high - speedly and parallel architecture. however, in this thesis, it was applied to a low - speed and low power consumption system - a underwater long - range remote control reception system to realize decoding of remote control instructions in the frequency domain, and made the satisfactory result
一般來講， fpga多用於高速通信和高速信號處理領域，以發揮其處理速度快的特點，本文將其應用於一低速低功耗系統? ?某水下遠程遙控接收系統，主要用其在頻域來實現水下遠程遙控的解碼，取得了令人滿意的效果。 -
