    • PURPOSE: To provide a CDMA adaptive array antenna receiver with which an arithmetic amount of an adaptive update algorithm to calculate an antenna weight coefficient is remarkably reduced so as to lighten the processing load on a DSP. CONSTITUTION: Since no correlation exists between fingers in the CDMA communication system, the adaptive update algorithm used to calculate the antenna weight coefficient through the use of N-degree correlation matrix independently by each finger is equivalent to the adaptive update algorithm used to calculate an (NxL)-degree correlation matrix, and then each finger independently uses the adaptive update algorithm in a way of minimizing a square mean of common error signals by a sbutractor 8 after the synthesis by a rake synthesis circuit 6 so as to control the antenna weight coefficient. Thus, the arithmetic amount of the adaptive update algorithm used by all MMSE control circuits 5-1-5-L can considerably be reduced in proportion from (NL)2 to N2L so as to relieve the processing load of the DSP.
    • 目的:提供一种CDMA自适应阵列天线接收机,用于计算天线权重系数的自适应更新算法的算术量显着降低,以减轻DSP上的处理负担。 构成:由于CDMA通信系统中手指之间没有相关性,所以通过每个手指独立地使用N度相关矩阵来计算天线权重系数的自适应更新算法等同于用于计算( NxL) - 相关矩阵,然后每个手指独立地使用自适应更新算法,以便在由耙式合成电路6合成之后通过减法器8最小化公共误差信号的平方均值,以便控制天线权重系数 。 因此,所有MMSE控制电路5-1-5-L使用的自适应更新算法的算术量可以从(NL)2到N2L的比例相当大地减小,以便减轻DSP的处理负担。

    • PURPOSE: A linearly arranged digital beam forming antenna system with a side lobe blanking function is provided to eliminate unnecessary signals flowed in a side lobe by partially reusing signals received through a multi-receiving channel. CONSTITUTION: An array antenna(110), a multi-receiving channel(120), a signal generator(115), an analog-digital converter(130), a digital beam generator(140), and a comparator are prepared. The multi-receiving channel receives signals through a plurality of sub-arrays of the array antenna. The sub-arrays are stacked to form the array antenna. The comparator receives, processes, and compares a controlling signal and a digital beam output. The comparator verifies the received signals.

    • PURPOSE: An RFID antenna, an RFID antenna system including the same and a product management device are provided to suppress generation of a dark portion in a near field, thereby performing wireless access with an RFID tag located in a near field area. CONSTITUTION: An internal conductor(20) is inputted with a predetermined signal through one end. An outer conductor(40) surrounds the internal conductor. In the outer conductor, slots(42) are formed at predetermined intervals in a longitudinal direction. An end impedance device(60) is connected to the other end of the internal conductor, and has an impedance value for reflecting the signal. The predetermined interval is 1/2 of a wavelength of the signal. The outer conductor has a cylindrical structure where the internal conductor is located in a central axis. A long side of the slot has a rectangular shape parallel to the longitudinal direction.
