Abstract: A digital subscriber line receiving apparatus having resilience to HAM radio interference noise and a method therefore includes an automatic gain controller for amplifying a received signal level to a signal level having a predetermined magnitude, a timing recoverer for recovering timing from a signal output from the automatic gain controller, an equalizer for removing interference noise from a signal received from the timing recoverer, a slicer for detecting a digital value from a signal received from the equalizer, an initialization controller for resetting the receiving apparatus and initializing the automatic gain controller, the timing recoverer, and the equalizer when the signal to noise ratio of the output signal of the equalizer is smaller than a reference signal to noise ratio, and an update controller for preventing automatic gain controller and equalizer from being initialized by the initialization controller when HAM radio interference noise is detected in the received signal.
