Description of the Invention: [Technical Field of the Invention] The present invention relates to a wireless communication system, and more particularly to a multi-input and multi-out communication system. [Prior Art] In recent years, wireless communication systems have been developing in both directions of high speed and large bandwidth. However, to improve the speed, bandwidth and quality of transmission, the area covered by each base station will be reduced; therefore, if the network provider wants to provide wireless broadband communication services for the same area, the number of base stations is necessary. Compared with the current situation, the problem is not the cost issue. 'The distance between the base stations and the base station will cause serious multiple access interference problems, which will also affect the stability of data transmission. Therefore, in order to solve this dilemma, multiple in multiple out (hereinafter referred to as ΜΙΜΟ) communication technology can provide more stable data transmission, and the network capacity and bandwidth can be more effectively used. ΜΙΜΟ refers to the communication technology of installing multiple transmitting antennas and multiple receiving antennas at the transmitting end and the receiving end respectively, compared with the traditional single input single out pm (SIS0), through the transmitting end and receiving Multiple antenna transmission and reception at the end enables the system to transmit data at a higher rate within a limited bandwidth, which is a significant increase in throughput. However, most of the products currently used in the market are focused on Increase the maximum data throughput' or reduce the loss on the transmission (l〇ss), but there are still many dead ends for the receiving ability in different directions, which means that with the 201044693 « different products, the angle may be different In the month t*, there will be a situation in which the RF signal is not received, and thus the data throughput is unstable.
