MULTI-MODE SIGNAL RECEIVING SYSTEM AND RECEIVING METHOD THEREOF

摘要

PURPOSE: A multi-path signal reception system and a receiving method are provided to increase the accuracy of phase signal search and to compensate the phase of a signal. CONSTITUTION: A receiving unit(100) receives multi path signals through multi channel paths. Couplers(311,312,313,314) detect each phase in a plurality of signal paths. A switch(320) selects the receiving path of the detection signal of the coupler. A phase comparator(330) compares phases of the signal which is received through the other path. Phase shifters control the phase of a oscillator signal according to the control signal of a controller.
