摘要： An multi-port based MIMO antenna receiver is designed to remove signal interferences occurring among MIMO antennas in the use. In the MIMO antenna receiver, a multi-port unit is connected to MIMO antennas, and a signal interference remover receives receipt signals from the MIMO antennas through the multi-port unit and adds each of the receipt signals with another one of the receipt signals to which preset weight values for minimizing signal interference are multiplied in order to remove interferences from the receipt signals. A phase converter converts the signals from the signal interference remover into multi-phase signals of different phases. A signal detector detects I and Q signals from the multi-phase signals converted by the phase converter. A signal processor restores original data by using the I and Q signals detected by the phase converter, and a weight value calculator monitors the detection signals by the signal detector while calculating a weight value of each of the receipt signals with the detection signal corresponding to an optimum receiving condition.
