    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.

    Abstract: Exemplary embodiments provide a radar apparatus having a plurality of antenna elements and enabling to reduce a number of ADCs as long as being allowable according to a bandwidth of the ADC, reduce a chip area occupied by the ADC and interconnections in an integrated circuit, and prevent a synchronization problem between the ADCs by sampling receive signals of multiple channels at once. Frequencies of local oscillation signals used for downconverting receive signals are set to be different from each other by an amount of an offset frequency, so that each of band-limited receive signals obtained through respective RF paths may occupy a different position on a frequency axis of a frequency domain. Downconverted receive signals are combined into a single signal and converted into a single digital signal stream, and a signal processing of the digital signal stream in a digital domain enables to obtain target data.
