摘要：
We consider the joint design of the transmit and receive beamforming in transmit subaperturing multiple-input-multiple-output (TS-MIMO) systems by utilizing the prior knowledge about the locations and power of the target and inherent interferences. The joint design is solved by an iterative algorithm to maximize the output signal-to-interference-plus-noise-ratio (SINR). The proposed approach can benefit from the sum co-array and joint transmit and receive optimization. Simulation results show that the approach provides more directions of freedom (DOFs) and/or directional gain compared to the original TS-MIMO and omni-MIMO, which leads to better output SINR results and interference rejection.
