If we are to raise compressionspeed, then the algorithm complexity must increase.
如果要提高压缩速度，那么算法的复杂度就得增加了。

It has advantages of high compression rate, high compressionspeed, unchangeable signal and image characteristics after compression, and anti-interference under transmitting.
它的特点是压缩比高，压缩速度快，压缩后能保持信号与图像的特征不变，且在传递中可以抗干扰。
