中文摘要:

为了压制边带, multiband 引起直角的频率部门 multiplexing (MB-OFDM ) 的干扰基于认知收音机系统,边带信号的一个数学表达式被导出。基于这表情,在播送符号之中的限制,帮助压制干扰,被获得。与限制结合了,块涡轮代码调整计划的一种类型被建议。在调整计划,边带干扰快速被稀释。与另外的技术相比,在这个计划,干扰抑制更容易并且足够地被实现。同时,小点错误率(BER ) 表演能被改进。理论分析和模拟结果证明 MB-OFDM-based 认知收音机系统受不了瑞利褪色是高度适用的。

英文摘要:

To suppress the side-band interferences caused by multiband orthogonal frequency division multiplexing (MB-OFDM)-based cognitive radio systems, a mathematical expression of the side-band signal is derived. Based on this expression, the constraints among the transmitted symbols, which help to suppress the interferences, are obtained. Combined with the constraints, a type of block Turbo code modulation scheme is proposed. In the modulation scheme, the side-band interferences are attenuated quickly. Compared with other techniques, in this scheme, the interference suppression is implemented more easily and sufficiently. Simultaneously, the bit error rate (BER) performance can be improved. Theoretical analyses and simulation results show that it is highly applicable for MB-OFDM-based cognitive radio systems to suffer from Rayleigh fading.
