Interference potential of PC noises on MB-OFDM UWB systems

Since PC noises in the UWB frequency band mainly comprise the harmonics of clock signals, a numerical analysis is made on the influence of clock harmonics on the bit error rate (BER) of multiband OFDM (MB-OFDM) UWB systems. Results show that clock harmonics cause a considerable BER degradation when...

Summary:Since PC noises in the UWB frequency band mainly comprise the harmonics of clock signals, a numerical analysis is made on the influence of clock harmonics on the bit error rate (BER) of multiband OFDM (MB-OFDM) UWB systems. Results show that clock harmonics cause a considerable BER degradation when a UWB terminal is placed close to a PC. They further show that frequency modulation of a PC clock signal, so-called spread spectrum clocking (SSC), has no effect for mitigating BER degradation, though SSC techniques are commonly used in PCs for reducing the power spectral density of radiated clock harmonic noises
