代码说明:

  OFDM降低峰平比采用预失真技术,程序仿真了加入预失真技术后的星座图与未加预失真的比较。结果比较明显。采用QAM映射。(OFDM PAPR reducing the use of pre-distortion technology, process simulation technology to join the pre-distortion of the constellation diagram and the following not pre-distortion comparison. More obvious results.)

    说明:  自己用的小软件,仿造原子的XCOM功能,加了一下自己用的功能。 1、基本串口通讯,鼠标放入串口选择自动刷新,显示COM口的驱动类型。 2、多条发送界面,可定时发送,可关联数字键盘、右键发送按钮可更改按钮名称,方便记忆。 3、485通讯,数据有十进制和十六进制可选,发送后自动保留记录。 4、CRC校验小工具。 5、十六进制通信协议提取部分位并根据自定义数据类型转化为十进制 6、字符格式示波器,例:">P:-1.25",示波器显示曲线名称P,数值-1.25,曲线个数最多8个。 7、类似MODBUS协议截取第2-5位,合成一个int数值,然后示波器显示波形,最多5个曲线 8、示波器曲线可键拖拽、放大(QT serial port assistant, plus digital oscilloscope)

    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 ...)

    说明:  基于子空间投影的 CSMG 波束形成算法,是一种将子空间投影与波束形成技术相 结合的抗干扰方法。该方法首先构造干扰子空间的正交补空间,再将天线阵列接收到的空时信号矢量向其投影,然后对投影后的输出信号采用具有严格约束最小功率的抽样矩阵梯度(CSMG)算法,在固定方向上进行波束形成,最后捕获、定位及解算出每个波束得到的无干扰数据等,可以有效地抑制干扰信号,同时又可以更好的保留期望信号。(The algorithm of the CSMG beamforming based on subspace projection, which is a combination of the Subspace projection and beam forming technology. Firstly, the data vector received by antenna array is projected onto the interference subspace, which is orthogonal to interference subspace for achieving interference suppression. And then, by using the method of the strictly constrained minimum power sampling matrix gradient(CSMG), after the projection of the subspace, the signal is beamformed in a fixed direction. Finally, for jammer-free data of each beam achieved to capture, locate, solute and so on. The ability of the suppress interference by this method, which can be more effectively, and keep the desired signal better.)
