Abstract :
Multi-antenna has a great potential to improve the performance of wireless communication system due to its spatial multiplexing. In this paper, we investigate the Degrees of Freedom (DoF) of Wyner´s linear asymmetric channel where each transmitter connects to its own receiver and one successive receiver. The DoF regions of Wyner´s linear asymmetric channel for 2 users are provided when each node is equipped with arbitrary number of antennas. Meanwhile, the total DoF of this channel for arbitrary K users are obtained when transmitters and receivers are equipped with different number of antennas. For each case, the conditions with and without channel state information at transmitters are both studied.
