Abstract: In this paper, the error performance of on-off frequency shift keying (OOFSK)modulation over fading channels is analyzed when the receiver is equipped withmultiple antennas. The analysis is conducted in two cases: the coherentscenario where the fading is perfectly known at the receiver, and thenoncoherent scenario where neither the receiver nor the transmitter knows thefading coefficients. For both cases, the maximum a posteriori probability (MAP)detection rule is derived and analytical probability of error expressions areobtained. The effect of fading correlation among the receiver antennas is alsostudied. Simulation results indicate that for sufficiently low duty cyclevalues, lower probability of error values with respect to FSK signaling areachieved. Equivalently, when compared to FSK modulation, OOFSK with low dutycycle requires less energy to achieve the same probability of error, whichrenders this modulation a more energy efficient transmission technique.
