Abstract: Provided is a method and apparatus to adaptively set a threshold for signal demodulation. The apparatus and the method include adaptively setting a threshold to demodulate a currently received symbol based on the demodulation value of a previously received symbol based on a comparison value. The comparison value is obtained by comparing a number of previously received symbols having a demodulation value of “0” and a number of currently received symbols having a demodulation value of “1”.
