  1. In the third chapter, it was particularly analyzed the impact of the correlation between antenna arrays both sides of transmit and receive, the coexistence of line of sight ( los ) component and scatter power component in the radio propagation environments, and known and unknown channel state information on the capacity of mimo channel. the related simulation results are also given

    第三章著重分析了收發兩端的多天線單元之間存在相關性、同時存在直射分量（ los ）和散射分量的傳播環境、已知和未知通道的狀態信息等因素對mimo通道容量的影響，給出了有關模擬結果。
  2. Spin out 1 - on track for delivery to the army evaluation task force in 2008 - includes tactical and urban unattended ground sensors, the non - line - of - sight launch system, the joint tactical radio system and an early version of the fcs networked battle command

    一階段成果? ?按計劃將於2008年交付給陸軍的評估驗證部隊? ?包括可以獨立工作的城市地面戰術傳感器，非視線范圍內的發射系統，聯合戰術電臺系統以及一個早期版本的未來戰斗系統網路作戰指揮平臺。
  3. Frequency sharing criteria between line - of - sight radio - relay systems and space radiocommunication systems

    視距微波接力通信系統與空間無線電通信系統共用頻率的技術要求
  4. In cellular envirorunents, because of the influence of several adverse factors, such as muitipath, non - line - of sight propagation, noise, interference and channel frequency characteristics, radio statistics measuremenis like tdoa, toa and aoa related to mobile position, the performance of location algorithms mny be significantly degraded and the position estimation of ms is inevitably biased

    在蜂窩網路環境中，由於受多徑、非視距傳播、噪聲、干擾和通道頻率特性等多種不利因素的綜合影響，使tdoa 、 toa 、 aoa等與移動臺位置有關的電波特徵測量值不可避免地出現較大誤差，從而使各種定位演算法的性能顯著下降，造成移動臺位置估計出現較大偏差。
