Abstract: The present disclosure relates to a wireless communication apparatus capable of increasing throughput using MIMO in an LOS environment and a method for the same. A wireless communication apparatus based on the LOS-MIMO technique may comprise a multi-link configuration unit, a frequency response correction unit, a signal compensation unit, and a feedback unit. In the apparatus, an additional LOS-MIMO equalizer is used at the front of an LOS-MIMO estimator and a coding unit in order to compensate in-band frequency characteristics of frequency response characteristics estimated by the LOS-MIMO estimator and a signal channel estimator, whereby the LOS-MIMO estimation performance can be remarkably enhanced. Also, precise separation of multiplexed signals through the above-described LOS equalizer can make it possible to increase transmission capacity by using the LOS-MIMO which can be applied to high-order mode (e.g., over 16 quadrature amplitude modulation (QAM)) digital communications.
