In this paper, we consider the problem of interference alignment (IA) for the K-user SISO interference channel (IC) with no channel state information (CSI) at transmitters. Contrary to the traditional K-user interference alignment (IA) scheme introduced by Cadambe and Jafar, our achievement has more practical aspects. In the present work, each transmitter uses a specific precoder and every receiver is equipped with one reconfigurable antenna. Each pair of transceivers with the aid of a specific precoder and a switching pattern structure tries to place its desired signal in a subspace which is linearly independent of interference signals.
