Advantages of FSK in Smart Grid Applications

Robustness Against Power Line Noise

Te power line channel is riddled with impulsy noise from switing devices, harmonic distortion from nonlinear loads, and narrowband interference from radio frequency sources. FSK 's inherent frequency diversity allows it to tolerante difficiant noise levels. Because the modulation is based on frequency shifts rather than amitude changes, a sudden voltage spike may sationate thee redisequerver but will not dept thee frequency information.
