摘要

正交频分多址(OFDMA)已经成为3G长期演进(LTE)和4G的主要多址技术。分析了OFDMA多址技术的特点，提出了一种新的OFDMA切换算法(子载波双向阵列切换算法，SBA)。仿真结果表明，在切换过程中，本文提出的SBA算法保证了OFDMA系统中用户保持最佳的信道SIR和QoS。此外，SBA算法减少了切换的额外消耗，提高了OFDMA系统的性能。

Sub-carriers bidirectional arrayed handover algorithm

Orthogonal Frequency Division Multiple Access (OFDMA) has already been the main multiple access technology for 3G long term evolution(LTE) and 4G. This paper analyzes characteristics of OFDMA multiple access technology and puts forward a new OFDMA handover algorithm (sub-carriers bidirectional arrayed handover algorithm, SBA). The simulation results show that, during handover process, SBA algorithm proposed in this paper guarantees users in OFDMA system keeping the best channel SIR and QoS. Moreover, SBA algorithm decreases the extra consumption of the handover, and improves OFDMA system performance.
