The third generation wireless DS-CDMA networks are expected to support a wide varietyof multimedia services such as high quality voice and data continuous (facsimile). The systemquality of DS-CDMA is shown as bit error probability values or bit error rate (BER) both voicechannel and continuous data channel. Bit error probability values are influenced by interferenceof the other users voice and data continuous (facsimile) .In the Final Project is made the genetic algorithm software for measuring the optimalsystem quality, specially for reverse channel. The optimal value result to explain the numberactive voice and data users that results minimum probability value on voice channel or datacontinuous (facsimile).

DESIGN SPREAD SPECTRUM COMMUNICATION SYSTEM SIMULATION (Software) Andy Soeseno; Yoedy Moegiharto; Arna Fariza

Â Â Â Â Â Â Â Â Â Â Â In this paper was design direct sequence spread spectrum simulation program consist of include the program of pseudo noise code generator by using gold codes method, spreading and despreading program. The sequence of pseudo noise code generated in 7 chips for 5 bits binary data information and 15 chips for 4 bit binary data information. The program of spreading simulation can provides sequence of spread spectrum signal and the program of despreading can recovery the original information signal. Keyword : spreading , desprading, pseudo noise code, chip, gold codes.

Recently the CDMA communication system has been developed with an ability to keep the secret of the transmitted information and also immune toÂ interferences.Â Â Â Â Â Â Â Â Â Â Â In a CDMA system every user has an identification code which are mutually independent (orthogonal). To prove the orthogonality of the codes theÂ correlation process is used.Â Â Â Â Â Â Â Â Â Â Â In this final project, we simulate the correlation process by using the Hadamard-Walsh matrix codes. The correlation process that is used to prove the orthogonality will apply the XNOR calculation. The correlation processes consist of two i.e. autocorrelation and crosscorrelation in which autocorrelation process will always result in correlation coefficient that is larger than the crosscorrelation process.
