针对传统小波变换过程复杂的缺点和SPIHT 算法编码过程重复运算、存储量大的问题。首先分析了小波基 和小波分解层数的选取, 然后提出了一种改进的SPIH T 算法, 该算法利用可变阈值对SPIH T 算法中初始子带进行分类得 到一种更有效的编码算法。-Against disadvantages of traditional process of complex wavelet transform and SPIHT algorithm coding process repeated op

wavelet and subband coding provide notes regarding wavelet and various application with the coding.

Abstract The key of developing high frequency wideband communication system is how to model the HF wideband channel. Some HF wideband models are discussed and compared in this paper, including Vogler model, parallel subband model, two impro
