    数字基带传输基带信号,指未经调制的信号。这些信号的特征是其频谱从零频或很低频率开始,占据较宽的频带。 基带信号在传输前,必须经过一些处理或者某些变换(如码型变换、波形和频谱变换)才能送入信道中传输。处理或变换的目的是使信号的特性与信道的传输特性相匹配。 数字基带信号是消息代码的波形表示。表示形式有多种,有单极性、双极性波形,归零和非归零波形,差分波形、多电平波形之分,各自有不同的特点。 研究数字基带信号通过加性高斯白噪声信道的传输,并且假设信道除了叠加高斯噪声外,不会对信号产生其他失真。(matlabSimulation(pulse amplitude modulation) modulation signal in AWGN (additive white Gaussian noise AWGN (Additive White Gaussian Noise)) under the channel bit error rate and bit error rate performance, and compared with the theoretical value.)

  • SAR
    在实数域 ,对称、 正交的紧支集非平凡单小波基不存在 ,而多小波把紧支集,对称性、 正交性完美地结合在一起 ,使小波理论从标量扩展到矢量范畴。利用上述特点将多小波变换应用于 SAR 图像压缩。(In the real fields, symmetric, orthogonal set of nontrivial compactly supported wavelet basis does not exist alone, but more than the compact support wavelet, symmetry, orthogonality perfect combination, So wavelets theory extended Dao vector from scalar context. Use of these features will be more than SAR image compression wavelet transform.)
