Abstract
A transmitting apparatus in a communication system using a single radio frequency (RF) chain generates baseband signals to be transmitted, decomposes a steering vector of an antenna to generate a plurality of beam basis patterns orthogonal to each other, and maps the baseband signals into at least one baseband pattern using geometrical information of the plurality of beam basis patterns.

A method for mapping a baseband signal into a beamspace by a transmitting apparatus in a communication system using a single radio frequency (RF) chain, the method comprising:
- generating baseband signals to be transmitted;
- decomposing a steering vector of an antenna to generate a plurality of beam basis patterns orthogonal to each other;
- and
- mapping the baseband signals into at least one beam basis pattern using geometrical information of the plurality of beam basis patterns.
An apparatus for mapping a baseband signal into a beamspace in a communication system, the apparatus comprising:
- at least one processor that is part of one or more units including:
- a baseband signal processing unit generating baseband signals to be transmitted;
- a beamspace mapping unit decomposing a steering vector of an antenna to generate a plurality of beam basis patterns orthogonal to each other and mapping the baseband signals into at least one beam basis pattern based on geometrical information of the plurality of beam basis patterns and characteristics of the baseband signals;
- a single RF chain converting the baseband signals into a radio frequency (RF) band signal;
- and
- an antenna radiating a signal output from the single RF chain,
- wherein the at least one processor is configured to execute functions of the one or more units of which the at least one or more processor is a part.
