K. Veena Devi, P. Radhakrishnan, S. Prakash . VLSI Implementation of IDMA based Multiple Carrier Code Division Multiple Access for 4G Technologies. International Journal of Computer Applications. 70, 1 ( May 2013), 33-36. DOI=10.5120/11930-7708
Abstract
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 (MC-CDMA) 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 spreaded in frequency domain and transmitted on different subcarrier which eliminates frequency selective fading and show significant improvement in bit error rate performance. The existing system uses 1-dimensional interleaver for storing data from spreader. It has insufficient memory to interleave incoming data that provides bottleneck that reduces total system efficiency. To overcome this problem, a method called reconfigurable interleaver division multiple access (IDMA) based MCCDMA is proposed. It provides array type of interleaver that has multiple rows and multiple columns, so it can adapt to changes array based on incoming data. Thus it has efficiency to handle bottleneck by processing multiple data. Thus the throughput of the system will be increased.
