The method for beamforming in a wireless communication system comprises the steps of: receiving a sounding packet so as to estimate channel state information between a transmitter and a receiver; generating a beamforming matrix in accordance with the channel state information; generating a beamforming steering matrix by multiplying the beamforming matrix by a rotation matrix; and feeding back the beamforming steering matrix.

System and method for beamforming in a wireless communication system

A method for detecting radar signals comprises the steps of: receiving signals detected by a master device; receiving signals detected by a slave device; detecting radar pulses from the signals received by the master device; detecting radar pulses from the signals received by the slave device; and determining radar signals by combining the radar pulses detected by the master device and slave device.

Apparatus for detecting radar signals and the method thereof

A method for detecting radar signal comprises the steps of: receiving a signal by a receiver, wherein the strength of the received signal is controlled within a range; sampling the received signal so as to obtain a plurality of sampling values; dividing the sampling values into a plurality of segments; summing up the absolute values of the sampling values in each segment; and determining that the received signal includes radar signals if at least one summation is greater than a threshold.

Radar detection method and apparatus using the same

A method for detecting radar signal comprises the steps of: sampling a received signal so as to obtain a plurality of sampling values; taking an absolute value of the sampling values so as to obtain at least two parameters; and determining whether the received signal includes radar signals in accordance with the at least two parameters.
