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。 -
High frequency surface - wave radar ( hfswr ) utilizes the surface - wave mode of vertical polarization electromagnetic wave propagation over sea water to detect targets of ships and aircrafts at distance beyond the line of sight
高頻地波雷達（ hfswr ）依靠高頻垂直極化電磁波沿海洋表面繞射傳播的機理，實現對海面艦船目標和低空飛行目標的超視距探測。 -
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。
