    Abstract: An RF crossover structure includes a first and second independent transmission lines formed to cross with each other on a same surface of a dielectric substrate; first via-holes connected to the second transmission line so that the second transmission line is connected to a back surface from a front surface of the dielectric substrate and is connected again to the front surface of the dielectric substrate out of a crossing region at which the first and the second transmission lines are crossed. Further, the RF crossover structure includes CPW (Coplanar Waveguide) transmission lines used for a ground plane to improve a signal transmission property at the crossing region.

    Abstract: A communication method of a base station and a terminal based on interference alignment in a multi-cell multi-user multiple-input multiple-output (MIMO) interference channel and a method and apparatus of communication using interference alignment and block successive interference pre-cancellation in a multi-user MIMO interference channel. The base station may determine a precoding matrix to maximize a signal to interference and noise ratio (SINR) and a signal to leakage and noise ratio (SLNR) in the interference channel, and a terminal communicating with the base station may determine a decoding matrix to align interference. The transmitter including a multicell interference channel may calculate a rotation matrix for interference alignment, identify effective symbol vectors using the rotation matrix, and generate a transmit signal of a target transmitter to pre-cancel interference corresponding to a transmit signal of a neighboring transmitter.
