Performance analysis of a hybrid direct sequence / slow frequency hopping CDMA system in an indoor wireless slow Rician fading environment

The bit error rate of a hybrid direct sequence/slow frequency hopping system for DPSK modulation in a Rician fading radio channel in an indoor environment has been investigated with help of a theoretical model. We have considered the effect of selection diversity and maximal ratio combining on the performance. The effect of FEC coding on the performance was also part of the investigation. A comparison of the hybrid system with pure direct sequence has been made as well as a comparison with another model from literature. The bit error rate performance of hybrid DS/SFH systems, employing BPSK and QPSK as modulation techniques, is also discussed. In this way a comparison could be made of three systems, using the three mentioned modulation schemes. Finally, a throughput and delay analysis of a CDMA network using hybrid/ DS/SFH transceivers with DPSK modulation is presented in this report. A comparison of the throughput of the hybrid system has been compared with the throughput of a system based on direct sequence.Applied SciencesElectrical EngineeringTelecommunications and Traffic Control Systems Grou
