All conformance testing is performed at the same point. In the case where

45、 the GSM rejection filter is included (terminal category c), the measurements will be carried out in the front of the GSM rejection filter. In the case of a DVB-H receiver, the manufacturer shall provide the specified test mode in which the following parameters can be monitored: TS-BER after Viterbi

46、 decoder, TS-PER, MPE FER (FER) (Frame Error Rate before MPE-FEC), MPE-FEC FER (MFER) (Frame Error rate after MPE-FEC). 4.5 Degradation criteria and resynchronization Four different degradation criteria are used. The criteria a and b are used in the non-mobile cases for DVB-T. Criterion c is for mob

47、ile reception in DVB-T and criterion d for DVB-H reception A receiver must be able to acquire a degraded signal and a resynchronization test must be done to ensure the C/N or C/I value is valid. Once the degradation criterion is achieved, all receiver input signals are removed for a period of 5 seco

48、nds and then re-applied. The same degradation criterion must be achieved within a further 5 seconds. If that is not the case, then the only degradation criterion that can be used for receiver measurement has to be based upon successful signal acquisition. a) Reference BER, defined as BER = 2 104afte

49、r Viterbi decoding. This corresponds to the quasi error free (QEF) criterion in the DVB-T standard, which states: ”less than one uncorrected error event per hour”. In the stationary reception cases, QEF is equivalent to the reference BER after Viterbi decoding. b) Picture failure point (PFP). The picture failure point is defined as the C/N or C/I value when picture errors become visible. Thi
