基于IRA天线的辐射波模拟器天线辐射性能研究(Radiation wave simulator antenna radiation performance of the antenna-based IRA)

为了提高MIMO-OFDM系统的数据传输率和频谱利用率,提出一种新的自适应算法。该算法在保证信道质量所需误码率和总发射功率的前提下,按照各个子载波衰落程度动态地分配比特和功率,使系统的总数据传输速率最大。理论分析得出,该算法降低了系统运算复杂度,能很大地改善系统的整体性能。(In order to improve data transmission rates and spectrum efficiency of MIMO-OFDM systems,this paper proposes a new adaptive algorithm. While the channel transmission quality to meet the requirements of a certain target BER(bit error rate) and total emissive power,according to each sub-carrier decline degree to adjust each sub-carrier modulation method freely,try to minimize the total data rate of system. Theory analysis shows the algorithm can reduce system complexity and improve overall performance of the ...)

生成常见的混沌映射，用于混沌扩频码的设计。应用三种量化方法，比特量化、门限量化以及模2量化。重点计算其相关性能，自相关以及互相关，得到相关图像。计算序列的游程、平衡度。(To generate common chaos maps and use them to design the chaotic spreading sequences. We applied three kinds of quantization methods with bit queantization, threshold quantization and mod 2 quantization. We emphasized on the calculating the correlation performance on auto-corrrelation and cross-correlation and plotted their images.)
