    • Provided is a method for retransmitting data based on antenna scheduling in a MIMO system to which a spatial multiplexing technique is applied. The method includes the steps of: (a) at a transmitter side, modulating an input packet into transmittable data to transmit to a receiver side; (b) at the receiver side, estimating channel values from the packet transmitted from the transmitter side, and selecting transmitting and receiving antennas for transmitting the next packet from the estimated channel values; (c) detecting whether an error is present in the packet or not, and transmitting a feedback signal to the transmitter side, the feedback signal including information on whether or not to transmit the packet and a list of the selected transmitting antennas; and (d) at the transmitter side, retransmitting the transmitted packet or transmitting the next packet through the transmitting antennas designated by the receiver side depending on the feedback signal.

    • A digital phase interpolator including a plurality of delay stages to control delay time of an output signal from first and second input signals having different phase delays. The plurality of delay stages are connected serially, have a same internal structure, determine corresponding axes for interpolation in each stage, and each includes a first inverting section for inverting first and second signal inputs from the previous stage, a phase blender for blending outputs of the first inverting section, a second inverting section for inverting outputs of the first inverting section, and a multiplexer for generating input signals for the next stage in response to a selection signal for determining phase delay time of the output signal of the phase interpolator. Total area and current may be reduced by the present invention because the number of inverters comprising each stage is equal.
