Quadrature modulation - transceiver and parameters determining a method for iq is not equal to the weight of the calibration

摘要

Quadrature modulation - transceiver (200), comprising:a transmitter (210, 220) for receiving an inphase - component (i_t) and a quadrature phase - component (q_t) an input signal, and for generating a transmission signal (s_t) by upconverting of the inphase - component (i_t) according to any one inphase - transmission medium (s_It) and of the quadrature phase - component (q_t) according to a quadrature phase - transmission medium (s_Qt);grinding of a test component (270) which, with the transmitter (210, 220) is connected, in order to provide a test grinding parameters, in order to the transmission signal (s_t) to adjust, in order to grind a test signal (s_lb) to produce, wherein the test grinding component (270) a plurality of sets of test grinding parameters, wherein the test, a set of grinding parameters from the plurality of sets of test grinding parameters is selected;a receiver (230, 240), the grinding with the test component (270) is connected, for downconverting the test signal (s grinding_lb) according to any one inphase - reception carrier (s_Ir) and a quadrature phase - reception carrier (s_Qr), in order to obtain an inphase - proportion of (i_r) and a quadrature phase - proportion (q_r) a received signal (s_r) ; anda calibration unit (205), which, with the transmitter (210, 220) and the receiver (230, 240) is connected to produce the input signal, the received signal (s_r) to receive and a calibration parameters for the iq imbalance of the quadrature modulation - transceiver (200) to be calculated; characterised by:a first selector (250), the with the transmitter (210, 220) and grinding of the test component (270) is connected, in order to determine whether the transmission signal (s_t) in the test grinding component (270) is entered.
