International Telemetering Conference Proceedings / October 21, 2002 / Town & Country Hotel and Conference Center, San Diego, California / For faster acquisition in bursted environments for SMS (Short Messaging Service) and
other lower-bit rate applications, non-coherent detection techniques are proposed. Non-Coherent detection demodulators are proposed because faster acquisition capability in
bursted environments can result in a reduced amount of preamble bits in the messaging
frame, i.e. less overhead, resulting in an effective increase in spectral efficiency.
Reducing the preamble can also provide performance enhancement opportunities for
Feher Quadrature Phase Shift Keying (FQPSK) [1] and for other systems. The preamble
can also be varied to provide for better Bit Error Rate (BER) performance. The lower bit
rate environment also gives the opportunity to employ simpler architectures in lieu of
preamble modification. Several non-coherent detection alternatives are described.
