代码说明:

OFDM采用BPSK、QPSK、16QAM、64QAM4种调制方式。按照星座图,将每个子信道上的数据,映射到星座图点的复数表示,转换为同相Ich和正交分量Qch。 需要确定的参数为:子信道,子载波数,FFT长度,每次使用的OFDM符号数,调制度水平,符号速率,比特率,保护间隔长度,信噪比,插入导频数,基本的仿真可以不插入导频,可以为0。

    说明:  为了在抑制噪声时尽可能保留图像边缘信息,提出一种自适应各向异性高斯滤波器设计方法. 该方法由独立 强度传播(IDS)模型决定滤波器的长轴尺度,由像素的邻域平滑度决定长短轴的比例,然后根据该处的灰度梯度方 向自适应决定各向异性滤波器的长轴方向. 仿真实验表明,提出的自适应各向异性滤波器具有很强的噪声抑制和 边缘保持能力. (In order to suppress noise, as far as possible to keep the image edge information, an adaptive anisotropic Gaussian filter design methods. The method by the independent strength spread (IDS) model determines the long axis of the filter scale, the pixel neighborhood smoothness determine the ratio of minor axis, and then there' s gray gradient direction of adaptive decision the long axis of anisotropic filter. Simulation results show that the proposed adaptive anisotropic filter has a strong noise suppression and preserve edges.)
