一种基于移动台位置的动态定位算法。 : 根据检测电波到达时间( T O A ) 的定位法提出了一种基于移动台位置的动态定位算法。该算法利用蜂窝 网络系统中多个基站检测到的移动台电波 T O A信息对移动台进行定位估计, 参与定位估计的基站数 目及其定 位算法中相应的权值随移动台与服务基站的距离自动动态改变。计算机模拟结果表明, 该算法在 3 种典型移动 通信信道环境中部能得到较好的定位蚊果。-:I n t hi s p a p e r ,a d y n am i c p o s i t/o n i n g t l l m i s p r o p o s e d b a s e d O n t h e me a s u r e d t i me o f a r r i v a l ( " I D A)o f s a l s f r o m a m o b i l e s t a t i c ~ . s且 l t h r n c a i n b e u s e d i n c e l l u l a r n e t w o r k s t o e s t i m a t e t h e l o c a t i o n o f a mo b i l e s t a t i o n a c c o r d i n g t o出e T O A i n f o r ma t i c ~d e t e c t e d b y s e v e r a l b a s e s t a t i o n s( B S ) . n m r b e r o f B S a n d t h e c o r r e s p o n d i n g W e i g h t s u t i l i z e d i n t h i s t l l m C a l l b e d y T l a c a u y a d i u s t e d a c c o ~ l g t o t h e d i s t a

    The SL11RIDE is a low cost, high speed Universal Serial Bus RISC based Controller board. It contains a 16-bit RISC processor with built in SL11RIDE ROM to greatly reduce firmware development efforts. Its serial flash EEPROM interface offers low cost storage for USB device configuration and customer product specific functions. New functions can be programmed into the I2C by downloading it from a USB Host PC. This unique architecture provides the ability to upgrade products, in the field, without changing the peripheral hardware.-USB IDE solution

  • gbsbem(几何gbsbem)模拟可以用来发电
    GBSBEM(几何单反射椭圆模型)可以用来仿真功率-延迟-角度(pda-图)、功率延迟图、时间-角度的联合统计、波达方向的边缘特征和窄带衰落包络。适用于低层系统,包括微小区和微微小区、杂波绕射基站天线、发射机到接收机之间以及发射机和接收机的周围充斥着散射体的情形。由于其适用范围广泛且具有解析性质,揭示了空间无线信道不同特征间的相互联系,是进行研究的理想模型。-GBSBEM (geometric GBSBEM) simulation can be used to power-delay-angle (pda- Chart), power plans delayed, time-point joint statistics, DOA on the brink of decline and narrow envelope. Apply to the lower systems, including Microcell and Microcells, Clutter diffraction base station antenna, between the transmitter and receiver to the transmitter and receiver around the full scattering case. Because of its broad scope of application and analytic nature, Space Channel reveals the different features of the inter-linkages Research is the ideal model.
