    摘要: A switch is particularly advantageous for calibration of signal phase between transmitters, and other uses. The switch has a first data input adapted to input a transmit signal from a first transmitter, a first data output, at least one and preferably multiple bidirectional data ports, and a control input adapted to selectively couple in a first case the first data input to one of the bidirectional data ports, and in a second case one of the bidirectional data ports and the first data input to the first data output. By coupling one data port of the switch to a data port of another identical switch, a transmit signal from another transmitter can be ported to the first said switch, and both signals output to a feedback circuit that finds the phase difference and applies it to a new signal input to one of the transmitters. Beamforming and MIMO uses are also detailed.

    摘要: There is provided an apparatus, having a first local oscillator generate a first oscillation signal, a first mixer generating a transmit signal by mixing an input signal and the first oscillation signal, an observation receiver receiving a portion of the transmit signal, and applying, in a first operation mode of the apparatus, the received portion of the transmit signal such that a transmit signal component on a frequency of the first oscillation signal falls into a band-pass frequency of the observation receiver, and shift, in a second operation mode of the apparatus, the received portion of the transmit signal such that an oscillation leakage signal component of the first oscillation signal falls into the band-pass frequency of the observation receiver; and a compensation unit generating a compensation signal based on the band-pass signal of the observation receiver for compensation of the input signal.

    摘要: A method and mobile terminal are disclosed for use in a wireless communication system, in order to increase security of the mobile terminal when it is lost, stolen, or misplaced by a user. The method includes receiving a guard message at the mobile terminal, authenticating the guard message, locking at least one communication capability of the mobile terminal, and also securing at least some data that is stored in the mobile terminal. Initiation of the method requires inputting a personal identification code at a location separate from the mobile terminal.
