Abstract: 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 analog signal, and is transmitted to a receiver.

Abstract: The present invention provides hierarchical modulation methods for robust symbol transmission and reception in a wireless access system, and devices supporting same. A method for transmitting a hierarchically modulated (HM) symbol in a wireless access system, according to an embodiment of the present invention, comprises the steps of: generating a first symbol; generating a second symbol; generating an HM symbol by combining the first symbol and the second symbol; and transmitting the HM symbol, wherein the first symbol can be generated by means of a spatial multiplexing (SM) technique, a beam-forming technique, or a space-time coding technique and the second symbol can be generated by means of a spatial multiplexing (SM) technique, a beam-forming technique, or a space-time coding technique.
