Analysis of noncoherent orthogonal modulation for mobile computing

Approved for public release; distribution is unlimited. / Wireless communication is employed to connect mobile computers in a networked environment for information
exchange. In a tactical space, sensors and computers typically need to operate on-the-move while transmitting data
over both short and long distances in different terrain and conditions. The wireless communication is thus susceptible
to effects of Doppler shift and channel fading. In addition, when security and anti jamming features are required, such
as frequency-hopping techniques, then coherent signal detection is difficult and noncoherent modulation is used
instead.
Our study will focus on the bit error rate (BER) performance analysis of noncoherent orthogonal modulation,
specifically M-ary frequency-shift keying (MFSK) and code-shift keying (CSK) modulation, in both additive white
Gaussian noise (AWGN) and for a Rayleigh fading channel with Doppler shift. The potential applications include
communications between mobile computer-sensor devices, such as a mobile ground control station maintaining a
datalink with UAV. / Civilian
