Multicarrier Code Division Multiple Access is the most promising technique for high speed data transmission. However, the MC-CDMA signals are characterized by large peak to average power ratios (PAPR), which can reduce the system efficiency. In this paper PAPR reduction of an MCCDMA system using SLM technique is investigated for different modulation schemes. The binary phase sequences considere...

In this paper, the application of Wiener filtering to the detection of Multi-Carrier Code Division Multiple Access (MC-CDMA) signals is analyzed. An analytical model is developed to evaluate an MCCDMA system with a very large number of subcarriers. This model is compared with simulations for 8 and 64 subcarriers.

Z-complementary code set (ZCCS) are well known to be used in multicarrier code-division multiple access (MCCDMA) system provide a interference free environment. Based on the existing literature, direct construction of optimal ZCCSs limited its length. In this paper, we interested constructing all possible even lengths using Pseudo-Boolean functions. The maximum column sequence peakto-man envelo...

In this paper, a novel digital modulation technique called Multi-Carrier Code Division Multiple Access (MCCDMA) is analyzed. With MC-CDMA, each data symbol is transmitted at multiple subcarriers with each subcarrier modulated by “1” or “-1” based on a spreading code. Analytical results are presented on the performance of this modulation/multiple access scheme in the downlink of an indoor wirele...

This paper analyzes the spectral efficiency (total channel capacity per subband) of randomly-spread synchronous multicarrier code-division multiple-access (MCCDMA) channel subject to frequency-selective fading in the asymptotic regime of number of users and bandwidth going to infinity with a constant ratio. We analyze the spectral efficiency for uplink and downlink conditioned on subcarrier fre...

Recently, intense interest has focused on the transmission techniques which can support high data rate transmission over wireless channels for applications including wireless multimedia, wireless Internet access, and future-generation mobile communication systems. However, high data rate transmission is limited by inter-symbol interference (ISI) due to the frequency selective fading in multipat...

The aim of this paper is to design a transceiver that achieves a data rate of minimum 4Gbps equivalent to the 4G standard of IEEE. Multiple Carrier Code Division Multiple Access (MCCDMA) is the combination of code division multiple access (CDMA) and orthogonal Frequency Division Multiplexing (OFDM), therefore the advantages of both schemes can be achieved. In MC-CDMA scheme each data symbol is ...
