Abstract
A method and apparatus for pulse position demodulation begins by receiving a pulse that is positioned approximately at one of a plurality of time intervals within a time chip, where the pulse has a pulse width that is greater than each of the plurality of time intervals. The decoding process then continues by determining the time interval in which a transition edge of the pulse lies. From the particular time interval, a set of bits is determined.
