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. This phase compensated-digital signal is converted to an analogue signal, and is transmitted to a receiver.
