Abstract

The invention relates to a robust non-linear transceiver under a multiple-input-multiple-output spatial correlation channel. Firstly, the transceiver acquires a processing matrix of sending and receiving signals through a channel estimation module and a sending and receiving matrix computation module. The processing matrix comprises an emission precoding matrix, an emission feedback matrix and a receiving equilibrium matrix. A calculating result is output to the emission precoding matrix and the receiving equilibrium matrix so as to carry out processing of the sending and receiving signals. And then, the digital modulation signal is input to the emission precoding module and is output to the channel after being processed by the emission feedback matrix and the emission precoding matrix. A receiving terminal processes the received signals through the receiving equilibrium module and finally the signals are output through demodulation. By using the transceiver, system performance is better than the system performance acquired by using a linear transceiver under the condition of spatial related imperfect channel state information.

Description

technical field [0001] The invention relates to a device in the technical field of signal processing, in particular to a robust nonlinear transceiver device under a multiple-input multiple-output spatial correlation channel. Background technique [0002] The traditional wireless communication technology has reached an unprecedented level of research on the frequency domain, time domain and code domain information of the signal, but it still cannot meet the needs of the application. It is necessary to expand the new signal processing field, and the research on the signal space domain makes up for this. A blank, through the research of antenna diversity technology and smart antenna technology, it is found that it is feasible to use multiple antennas to realize signal transmission. With the deepening of research, it eventually evolved into the multiple-input multiple-output (MIMO) communication technology. MIMO technology, as the framework technology of the future generation of...
