Abstract

The embodiment of the invention discloses an optimization method of an MIMO antenna and a mobile terminal. The optimization method of the MIMO antenna comprises the following steps: the MIMO antenna at least comprises a main antenna and a diversity antenna, the main antenna and the diversity antenna receive a plurality of signals and compare channel coefficients of the plurality of signals, the signals with the same channel coefficient are the same signals, distinguishing signals are demodulated, and the distinguishing signals and the same signals have different channel coefficients. Accordingto the scheme, the self-interference problem caused by the same spatial channel coefficient in the communication process of the MIMO communication system is reduced, the MIMO transmission capabilityis improved, and the MIMO throughput performance is improved.

Description

technical field [0001] The present invention relates to the technical field of antennas, in particular to a MIMO antenna optimization method and a mobile terminal. Background technique [0002] As an important technical means of 5G communication, MIMO (Multi Input Multi Output) technology is increasingly considered as an important indicator in design. MIMO technology means that the capacity and spectrum utilization of the communication system can be doubled without increasing the bandwidth. In MIMO technology, the receiver and transmitter are equipped with multiple antennas for communication at the same time, such as figure 1 As shown, the transmitting end transmits two signals X1 and X2 with two antennas at the same time, and the throughput is doubled; the quality of MIMO performance is very dependent on the quality of the MIMO channel model, that is, after the two signals are transmitted through the space, they are transmitted by the terminal After receiving the two ante...
