Based on a direct-conversion architecture,the receiver integrates LNA,I/Q mixer,DC-offset removal filter,baseband amplifier and channel-select filters on a single chip.
基于直接下变频的系统架构,接收机集成了低噪声放大器、I/Q下变频器、去直流偏移滤波器、基带放大器和信道选择滤波器。
Based on the combination of the adjacent diffusion method and the selective smoothing filter,a new anisotropic diffusion algorithm for image enlargement is proposed,which is called as the adjacent diffusion and selective smoothing algorithm(ADASS).
提出了一种新型的各向异性扩散图像放大的邻域扩散选择平滑法(ADASS),将邻域扩散法与选择平滑滤波器相结合,降低了算法的复杂度,并提高了图像的放大质量。
