PRE-COMPENSATION OF THE PHASE SHIFTING ERROR

摘要

In this disclosure, methods for pre-compensation of the phase shifting error, and apparatuses for the same are disclosed. In one example, a device performs precoding of a digital signal, while acquiring information on an error caused by a phase shifting of the precoding. Then, the device performs phase compensation on the digital signal based on the acquired information. Here, the phase compensation may compensate different amount of phase based on an amount of the phase shifting of the precoding. This phase compensated-digital signal is converted to an analogue signal, and is transmitted to a receiver.

1. A method for a transmitting device transmitting signals in a mobile communication system using multiple antennas, the method comprising:
precoding a digital signal; acquiring information on an error caused by a phase shifting of the precoding; performing a phase compensation on the digital signal based on the acquired information, wherein the phase compensation compensates different amount of phase based on an amount of the phase shifting of the precoding; converting the phase compensated-digital signal to an analogue signal; and transmitting the analogue signal to a receiver.
