Abstract

The present disclosure relates to a method and an apparatus for optimizing signal shaping of a multi-user multiple-input multiple-output (MU-MIMO) communication system.

Description

technical field [0001] Various example embodiments relate to a method and apparatus for optimizing signal shaping of a multi-user multiple-input multiple-output (MU-MIMO) communication system. Background technique [0002] Communication systems such as multiple-input / multiple-output (MIMO) communication systems are known systems that use multiple antennas at the transmitter and receiver and advanced digital signal processing to improve link quality and capacity. MIMO communication systems are used to use multiple transmit and receive antennas to exploit multipath propagation to double the capacity of a radio link. By exploiting multipath propagation, MIMO facilitates sending and receiving more than one data signal on the same radio channel. [0003] With MU-MIMO, a base station is equipped with multiple antennas and simultaneously serves multiple single-antenna users. It should be noted that spatial multiplexing is achieved by multiple antennas at the base station, which a...
