Abstract

The invention discloses an MIMO-EDM wireless communication system and method. The MIMO-EDM wireless communication system comprises a hybrid system and a separation system. Multiple-input multiple-output technology and MIMO technology are combined, and multiple paths of signals can be separated from entropy domains by using an entropy division multiplexing algorithm. The MIMO-EDM wireless communication method comprises the following processes: transmitting n paths of source signals; receiving the aliasing signals through a receiving end; and separating the multiple paths of aliasing signals through the separation system. According to the MIMO-EDM wireless communication system and method, the utilization rate of spectrum resources and the capacity of wireless channels are improved; negentropy is used as the criterion of statistical independence, and the separation of the multiple paths of aliasing signals is realized in the information entropy domains for the first time; and high-speed and high- quality broadband wireless communication is realized.

Description

technical field [0001] The invention belongs to the technical field of wireless communication, and in particular relates to a MIMO-EDM wireless communication system and method. Background technique [0002] With the rapid development of wireless communication technology, the user's demand for wireless communication is also increasing, and the wireless communication system itself is a resource-constrained system, which leads to the problem of extreme shortage of spectrum resources. How to effectively solve this problem has become a common concern of communication workers all over the world. The channel multiplexing technology can effectively solve this problem. The so-called multiplexing (Multiplexing) refers to the combination of multiple source signals into a composite signal in a certain way, and then transmit it on the same information transmission channel, and use certain criteria to separate them at the receiving end and receive them separately. . In the channel mult...
