Abstract
A method and apparatus for pulse position modulation begins when a digital data stream is received. The encoding process continues by obtaining a set of bits from the digital data stream and modulating the set of bits into a pulse having a pulse width. Next, a transition edge of the pulse is positioned at one of a plurality of time intervals within a time chip based on the set of bits, wherein the pulse width is greater than each of the plurality of time intervals.
