OOFSK信令多信道接收性能分析
Performance Analysis for Multichannel Reception of OOFSK Signaling
摘要：
本文分析了在衰落信道下，当接收机配置多天线时，开关频移键控（OOFSK）调制的误码性能。该分析是在两种情况下进行的：相干的情况下，衰落是完全已知的接收机，和非相干的情况下，无论是接收机还是发射机知道的衰落系数。对于这两种情况，推导了最大后验概率（MAP）检测规则，并得到了错误概率的解析表达式。研究了接收天线间衰落相关的影响。仿真结果表明，对于足够低的占空比值，实现了相对于FSK信令的较低的错误值概率。同样地，当与FSK调制相比时，具有低占空比的OOFSK需要更少的能量来实现相同的错误概率，这使得该调制成为更节能的传输技术。
英文摘要：
In this paper, the error performance of on-off frequency shift keying (OOFSK) modulation over fading channels is analyzed when the receiver is equipped with multiple antennas. The analysis is conducted in two cases: the coherent scenario where the fading is perfectly known at the receiver, and the noncoherent scenario where neither the receiver nor the transmitter knows the fading coefficients. For both cases, the maximum a posteriori probability (MAP) detection rule is derived and analytical probability of error expressions are obtained. The effect of fading correlation among the receiver antennas is also studied. Simulation results indicate that for sufficiently low duty cycle values, lower probability of error values with respect to FSK signaling are achieved. Equivalently, when compared to FSK modulation, OOFSK with low duty cycle requires less energy to achieve the same probability of error, which renders this modulation a more energy efficient transmission technique.
