Method and apparatus for splitting received signal

摘要

A method and apparatus for splitting signals received via a plurality of antennas. A signal split apparatus of the present disclosure includes a first antenna which receives a first input signal, a second antenna which receives a second input signal, a first phase shifter which shifts phase by applying a first modulation frequency to the first input signal, a second phase shifter which shifts phase by applying a second modulation frequency to the second input signal, a summer which sums the phase-shifted first and second input signals, and an analog-digital converter which converts the summed signal to a digital signal, wherein the first and second modulation frequencies are different from each other. The signal split apparatus and method of the present disclosure is capable of splitting signals efficiently.

1. A signal split apparatus comprising:
a first antenna configured to receive a first input signal; a second antenna configured to receive a second input signal; a first phase shifter configured to shift a phase by applying a first modulation frequency to the first input signal; a second phase shifter configured to shift a phase by applying a second modulation frequency to the second input signal; a summer configured to sum the phase-shifted first and second input signals to form a summed signal; and an analog-digital converter configured to convert the summed signal to a digital signal, wherein the first and second modulation frequencies are different from each other.
