Abstract
Provided is an STBC transceiving system with LPA-based beamformer, including: an STBC encoder having branches, in number of D, to generate output signals in number of D for an input signal; a beamformer having output antennas in number of D*B, being comprised of beam-forming subarrays in number of D each having the output antennas in number of B to form a downlink beam from the D-numbered output signals of the STBC encoder; and an STBC decoder restoring an original signal by dividing a signal, which is received as one with signals transmitted through a mobile antenna from the D-numbered beam-forming subarrays, into signals in number of D in accordance with the subarrays in consideration of channel characteristics.
