Multicarrier Code Division Multiple Access is the most promising technique for high speed data transmission. However, the MCCDMA signals are characterized by large peak to average power ratios (PAPR), which can reduce the system efficiency. In this paper PAPR reduction of an MC-CDMA system using PTS technique is investigated by using suboptimal combination algorithm, which uses binary phase fac...

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...

In this paper, we made a comprehensive study to evaluate the performance of a multi-user MIMO MCCDMA wireless communication system. The channel encoded spatially multiplexed MIMO MCCDMA system under investigation incorporates four linear signal detection schemes (Equalizers) such as Minimum Mean Square Error (MMSE), Zero Forcing (ZF), Sphere Decoding and Q-less QR Decomposition under BPSK, DPSK...

Abstract— Multi-carrier code division multiple access (MCCDMA)systems receive a great deal of attention due to their great potential in achieving high data rates in wireless communication. This paper presents the simulation and analysis of MC-CDMA system over orthogonal frequency division multiplexing technique. performance when the data is sent and received over AWGN channel and Rayleigh chann...

Multi-Carrier Code Division Multiple Access MC-CDMA is a promising technology for supporting high data rate in next generation wireless networks. By combining MCCDMA technology with Multiple-Input Multiple-Output (MIMO) spatial mssultiplexing, data transfer rate can be enhanced. However, the performance of MCCDMA technology is limited by the multiple-access Interference (MAI) and InterCarrier I...

The multi-carrier code division multiple access (MCCDMA) is a attractive choice for the future wireless systems where multiplexing and diversity in space, time and frequency are joined together through multiple input multiple output (MIMO) and space time block coding (STBC) in order to increase user capacity. In this study, the orthogonal complete complementary (OCC) spreading codes are employe...

Wideband Multicarrier code division multiple access (MCCDMA) and Rake receivers for wavelet video transmission with four levels of unequal error protection (UEP) codes over additive white Gaussian noise (AWGN) and Rayleigh fading channels are performed and evaluated. The deployment of Wavelets has approached a powerful technique and high quality for compressing video sequence. A spatially scala...
