Abstract
A method for increasing data rates within a modulated signal is disclosed. Initially, a first and second bit streams are interleaved together to form an interleaved output bit stream. The interleaved output bit stream is modulated in a manner such that upon demodulation of the interleaved output bit stream according to an FSK modulation scheme only the first bit stream is recovered, and upon demodulation of the interleaved output bit stream according to a second modulation scheme, both the first and second bit streams are recovered.
