Techniques and apparatus are described for detecting a position of a target. A position detection device associated with a wireless communication system includes an accumulator to sample and accumulate a pulse signal included in an input signal. A double-sliding window is connected to the accumulator to detect a starting point of the input signal. Also, a synchronization controller is connected to the accumulator to generate a synchronization signal to enable the accumulator to sample and accumulate the pulse signal. In addition, a time shift calculator is connected to the accumulator to correct the detected starting point of the input signal based on the accumulated pulse signal. Further, a position calculator is connected to the time shift calculator to calculate a position of a target based on the corrected starting point. |
