| Abstract | The performance of MC-CDMA system based on two-dimensional wavelet transform has been analyzed and tested in AWGN and multipath fading channel. The proposed structure was suggested by replacing the blocks of FFT in conventional model by a two dimensional wavelet transform blocks at the transmitter and receiver sides. This can be done by converting blocks of 64 bit of 1-Dimensional vector into 2-dimensional matrix and process it by 2-Dimensional wavelet transform. The output data and training vectors are multiplied by a generated phase matrix of size 64*64 bits at the transmitter side, and then the reverse procedure will apply to retrieve the transmitted data. The simulated results compared with the performance of MC-CDMA based on Multiwavelet transform (MWT) which outperforms the conventional models based on FFT and wavelet transform (WT). A gain of 2dB obtained at the AWGN channel, while in multipath fading, the obtained gains are 5dB and 2.5dB at Doppler frequencies of 5Hz and 200Hz respectively when the paths gain of −8dB. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
