摘　　要：由于LTE采用了OFDM(正交频分复用)技术,各载波间相互正交,因而小区内部的干扰可以基本消除,但相邻小区间的使用相同频率仍然会产生较大的干扰,影响系统频率复用效率,降低系统吞吐效能。因此,针对这一问题提出了基于遗传算法的频率复用思考,从而提高频率的利用效率同时降低相邻小区间的频率干扰,优化系统吞吐量,提高服务质量。Since the LTE uses OFDM（Orthogonal Frequency Division Multiplexing） technology, orthogonal to each other among the carriers, and thus the internal cell interference can be substantially eliminated, but the use of the same frequency between adjacent cells still produce large interference, affecting the system frequency reuse efficiency, reduces the system throughput performance. Therefore, to solve this problem is proposed frequency reuse thinking based on genetic algorithms to improve the frequency utilization efficiency while reducing frequency interference between adjacent cells to optimize system throughput, improve service quality.
