Abstract :
Delay profile measurements made on urban streets using double-phase-shift keying (DSK) were compared with the bit error rate (BER) performance to analyze the cause of burst errors due to multipath propagation. Two types of correlators were used to calculate the delay profile for different purposes. Multipath delay has been observed to depend on the environmental conditions with maximum up to 5 μs and delay spread less than 1.6 μs. The major reflecting objects were identified that cause long delayed waves in correspondence to the measured DSK BER performance. From the comparison of delay profile measurements with BER performance of DSK, it has been found that the BERs are markedly reduced as long as the delay time does not exceed a half timeslot of DSK signal and a sufficient C/N is attainable
