Hema Kale, C. G. Dethe, M. M. Mushrif

摘要:

在第四代无线通信系统中,多载波码分多址(MC-CDMA)技术正成为一种非常重要的高速数据传输的下行链路多址技术。通过有效的资源分配,可以实现更高的数据率,即吞吐量。本文评估的标准用于组(子信道)分配在下行链路传输,从而导致吞吐量最大化的性能。该算法给出了MC-CDMA系统下行链路子信道分配的改进技术。对三种合并方案进行了仿真,结果表明,在给定的功率和误码率下,所提出的算法具有更好的效果

英文摘要:

The Multi-Carrier Code Division Multiple Access (MC-CDMA) is becoming a very significant downlink multiple access technique for high-rate data transmission in the fourth generation wireless communication systems. By means of efficient resource allocation higher data rate i.e. throughput can be achieved. This paper evaluates the performance of criteria used for group (subchannel) allocation employed in downlink transmission, which results in throughput maximization. Proposed algorithm gives the modified technique of sub channel allocation in the downlink transmission of MC-CDMA systems. Simulation are carried out for all the three combining schemes, results shows that for the given power and BER proposed algorithm comparatively gives far better results
