METHOD AND APPARATUS FOR MODULATING BASEBAND SIGNAL IN BEAM SPACE MULTI-INPUT MULTI-OUTPUT, AND METHOD FOR RECEIVING THEREIN

摘要

A modulation method of a baseband signal, an apparatus thereof, and a receiving apparatus thereof in a beam space MIMO are disclosed. The baseband signal modulation apparatus may calculate a load value of a plurality of antenna elements by using the baseband signal. Also, the baseband signal modulation apparatus may change the phase or the magnitude for the baseband signal or a first band signal of a higher frequency than the baseband signal by corresponding to the frequency of the baseband signal.

1. A baseband modulation apparatus comprising:
an antenna array including a plurality of antenna element and irradiating a beam space MIMO (Multi-Input Multi-Output) signal; a baseband unit generating a baseband signal; a band converter converting the baseband signal into a first band signal of a higher frequency than the frequency of the baseband signal; a load calculator calculating a load value of the plurality of antenna elements by using the baseband signal and setting the calculated load value to the antenna array; a signal changing controller setting a changing value for at least one value among the phase and the magnitude of the baseband signal by corresponding to the frequency of the baseband signal; and a signal change unit signal-changing at least one among the baseband signal and the first band signal by corresponding to the changing value.
