Research on a real time measure method of quality of service in CDMA system

AimTo measure QoS of CDMA system in real time and not interrupting services, two measuring methods of bit error ratio(BER)were presented.Methods Two ways,one via software and the other via single-chip processor, were described. The program flow and hardware figures were presented also.Results The first method has the advantages of not interrupting services,no need for special devices and stronger in real time,but just a sub-procedure ware needs to be added.The second way needs a single-chip circuit and has an advantage of independence.ConclusionThe two methods both have following advantages:easy to operate,simple in designing,practicality for operators.
