Abstract: In this paper,the frequency domain space-alternating generalized expectation-maximization(FD-SAGE)algorithm is extended to the joint transmit-receive polarization multiple-input multiple-output(MIMO)case in order to determine the 3-D angular,temporal and polarization channel characteristics in joint transmit-receive radio link.Synthetic environments are generated to testify the efficiency of the proposed algorithm in a severe polarization multi-path indoor scenario.The results reveals that the proposed algorithm demonstrates an effective identification of the joint transmit-receive polarization MIMO channel and have stable performance.
