| 中文摘要: |
| 为了使系统的总功率达到最小,研究了OFDM子载波分配算法,采用遗传算法分配子载波。提出了一种有效的交叉算法并且将遗传算法进行了改进,有效保证每个用户的传输,改进后优于其它算法,能达到资源分配的最佳效果。它易于实现,效果明显,它比其它传统的优化算法有更优越的性能。 |
| 英文摘要: |
| In order to systemic power achieving minimum, a subcarrier allocation method is studied about OFDM and genetic algorithm is adopted. A efficient algorithm is proposed to crossover algorithm and genetic algorithm also is improved. It can ensure every user transmit information effectively. This algorithm is superior to other algorithm and achieved optimum efficiency on allocation of resources. It is easy to implement and its effect is obvious. Furthermore, it has more superior performance. |
