摘要
In this paper, the error performance of on-off frequency-shift keying (OOFSK) over fading channels is analyzed. A closed-form expression for the probability of error is obtained as a function of the instantaneous signal-to-noise ratio (SNR) when OOFSK signals are received over a coherent Rician fading channel. It is shown in simulation results that error performance improves especially at low SNR values as the duty cycle decreases. The error performance is also studied when the channel is assumed to be unknown at both the transmitter and receiver. For this case, the optimum detection rule is identified and analytical expressions for the probability of error are obtained. Similarly, it is concluded that probability of error decreases if one operates with lower duty cycle.
