A null detector and its corresponding method are provided. The null detector includes a power detector, a smoother, and an overlapper. The power detector outputs a power level signal according to the power level of a received signal. The smoother is coupled to the power detector for determining according to the power level signal whether the received signal is transmitting a null symbol, and then the smoother outputs a null detection signal at a first state value or a second state value indicating the result of the determination. The overlapper is coupled to the smoother for providing the duration and position of the null symbols transmitted by the received signal according to the null detection signal.
