| dc.description.abstract | As an effect of the globalization era, telecommunication technology, especially in wireless communication system is forced to prepare high data rate with reliable Quality of Service (QoS) with Low Bit Error Rate (BER) and very small power). The problem in mobile communication is mahipath fading, which affected the rising of error data receive on receiver sade Multi Carrier-Code Division Multiple Access (MC-CDMA) system is a combine technique between multiple access techniques with Orthogonal Frequency Division Mahiplexing (OFDM). The using of MC-CDMA will make frequency selective fading change into flat fading, so the process for overcoming the fading effect is easier. Beside the ability to overcome multipath fading, & abo makes the use of bandwidth more efficient. The channel coding technique is needed to overcome random error which routed by multipath fading. This final project simulates the Regular coding technique's performance Regular Low Demity Parity Check (LDPC) on MC-CDMA system by modified scheme using MATLAB 7.0.4 software. The simulation result is analyzed about the compare number of bit '1' effect the effect of variant size of block code, number of decoding iteration and the effect of user's TA
The simulation resuh showed that LDPC Coded MC-CDMA system with Regular coding technique 63 dB. In every compare variation regular LDPC has better performance than Uncoded | en_US |
