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 ...)

1．利用RBF神经网络，解决异或问题： 1）异或问题本质上是一个二分类问题:输入为向量[x1,x2],输出是标量，取值限定为0或1.(1. Use RBF neural network to solve different or problems: 1) an xor problem is essentially a binary problem: the input is a vector [x1,x2], and the output is a scalar whose value is limited to 0 or 1.)
