In 1993 some hybrid technics combining OFDM and code division multiple access (CDMA) were proposed [3]. One of that technics is multicarrier code division multiple access (MCCDMA) witch introduce frequency spreading and multiple access. Both, OFDM and MCCDMA, have disadvantage in high peak to average power ratio (PAPR). There are many PAPR reduction schemes are for OFDM and most of them is usef...

The latest technology in cellular mobile communication systems has become more demanding for better quality of service. It requires broad bandwidth for huge data transfer. In this paper, we compare the performance of Direct Sequence Code Division Multiple Access (DS-CDMA) and MultiCarrier Code Division Multiple Access (MC-CDMA) which are the major contenders for the next generation wireless sig...

In this paper the performance evaluation has been done for combinatorial code for different system and code parameters under noisy optical channel conditions for potentially increasing number of users for optical code division multiple access system. It has been observed that code weight and effective power from each user are two main factors to decide the system performance. KeywordsOptical Co...
