摘要： A smart antenna (figure 2) i.e., blind adaptive antenna array, is a method and system to suppress multiple access interference and to improve performance, for example in a code division multiple access (CDMA) wireless communications system, including third generation (3g) cdma2000 and wide band (W)-CDMA. A convergence parameter is employed in a smart antenna processor (207). In general, a constant convergence parameter value is empirically determined and used after studying the convergence speed and the steady state mean square error (MSE) or other performance data, such as bit error rate. As the convergence parameter would yield poor performance when the channel environment changes, which is true particularly when a mobile user moves around. In the present invention, the convergence parameter value is adaptively changed and employed in a smart antenna processor (207). Two exemplary methods to update the convergence parameter are described. By employing such an adaptive convergence parameter value, convergence speed can be increased and the steady state MSE can be decreased.

摘要： Power is conserved in a Global Positioning System (GPS) receiver by shutting down selected components during periods when the GPS receiver is not actively calculating the GPS receiver location. A low power time keeping circuit accurately preserves GPS time when the selected components are deactivated. When the selected components are turned on in response to a wake-up command, time provided from the low power time keeping circuit, corrected for actual operating temperatures, and data from the GPS clock temperature/frequency table, are used to recalibrate time from a GPS oscillator. Positions of the GPS satellites are then estimated such that the real GPS time is quickly determined from the received satellite signals. Once real GPS time is determined from the detected satellite signals, the selected components are deactivated. The process described above is repeated such that accurate GPS time is maintained by the low power time keeping circuit.

摘要： A method of controlling multiple antenna signal transmission is disclosed. The method includes adjusting signal parameters so that transmission signals from a plurality of antennas combine to form a directional beam. A time duration in which the transmission signals are directed is controlled so that an average EIRP does not exceed a predetermined threshold.

摘要： A communications device for separating source signals provided by M signal sources includes an antenna array comprising N antenna elements for receiving at least N different summations of the M source signals. A code despreader is connected to the N antenna elements for decoding the at least N different summations of the M source signals. Each one of the N different summations includes k codes for providing k different summations of the M source signals associated therewith. A blind signal separation processor forms a mixing matrix comprising at least kN different summations of the M source signals, and separates desired source signals from the mixing matrix. The mixing matrix has a rank equal up to kN.

摘要： Verfahren zum Bestimmen der Funkempfangsrichtung (D) in Abwärtsrichtung (DL) an einem mehrere Funkversorgungsbereiche (S1,S2,S3) umfassenden Funkfeststationsstandort (BS) in einem Mobilkommunikationsnetz, bei dem in jedem Bereich (S1) in der Abwärtsrichtung (DL) Funksignale mittels einer Sendeantenne (1) zum Empfang durch mindestens ein Mobilkommunikationsendgerät (MS) abgestrahlt werden. Zur Bestimmung der Funkempfangsrichtung (D) werden von dem jeweiligen Mobilkommunikationsendgerät (MS) zumindest die Empfangspegel der Funksignale gemessen, die von einer ersten und von einer zweiten des Sendeantennen abgestrahlt werden. Dabei wird aus den beiden gemessenen Empfangspegeln ein Verhältniswert gebildet, der unabhängig ist von den herrschenden Funkausbreitungsbedingungen und es wird mittels dieses Verhältniswertes eine Schätzung von Azimutwinkeln (A) für die zu bestimmende Funkempfangsrichtung (D) durchgeführt.
Das Verfahren lässt sich also an jedem einzelnen Funkfeststationsstandort durchführen, wobei kein Kontakt zu mehreren Funkfeststationen notwendig ist. Durch das Berechnen eines Verhältniswertes werden Einflüsse eliminiert, die von sich ändernden Funkausbreitungsbediungungen herrühren können.摘要翻译： 由天线发送的下行无线电信号的接收电平由移动通信终端（MS）测量。 在接收电平之间估计比值，以估计用于确定无线电接收方向（D）的方位角。 还包括以下独立权利要求：（1）移动通信网络; （2）电脑; （3）无线电基站; 和（4）移动通信终端。

摘要： A signal detector receives multiple segments of a signal, where the segments are from separate and distinct time periods. The signals arrive at a receiver (30), which passes them to a correlator (34). The correlator (34) correlates the received signals with hypothesis outputs of the expected contents of the segments. These hypothesis outputs are from a hypothesis generator (32). The correlated output of the correlator (34) is fed to a combiner (36), which outputs the correlated signal. The combiner has an additional output back to the receiver (30) by which it may request additional received segments.
