Abstract
A statistical parameter of disturbance is effective to estimate BER degradation of a digital link due to the disturbance. For the statistical parameter, an amplitude probability distribution (APD) gives a characteristic of the amplitude domain of the disturbance, and, furthermore, a crossing rate distribution (CRD) and a pulse duration distribution (PDD) give time domain characteristics. It has been reported that BER degradation of a digital link such as PHS or PDC due to disturbances emitted from microwave ovens can be estimated from the APD data of the disturbance. It is also necessary to obtain the CRD and PDD data of disturbance in order to make a digital link which has countermeasures against burst noise by using interleave techniques, etc. In this paper, APD/CRD/PDD measuring equipment is introduced and demonstrated.
