Desain Program Simulasi Unjuk Kerja Kode Walsh Pada Kanal Multipath Fading

: The purpose of this study was determine the effect of changes in the number of multipath components on the performance of the Walsh code on multipath fading channels through simulations using Matlab software where the simulation results are viewed from values and graphics Bit Error Rate ( BER ) versus Energy Bit per Noise (Eb / No). From the simulation it will be seen a comparison of the performance of the communication system of the Walsh code performance on the multipath fading channel generated by varying the number of multipath components by the number 2, 4, 6 and 8. This system is compared by first simulating using a flat fading channel in ideal conditions. The results of the simulation show that the performance of the Walsh code performance communication system on multipath fading channels has increased BER value when the number of multipath components is added. This is due to the greater number of multipath components to be used, so the greater number of reflected signals will interfere with the desired signal at the receiver.
