For reducing boundary distortion area, the elevations of grid DEM are viewed as a discrete sequence under a generalized coordinate, so that the boundary problem of two-dimensional discrete wavelet transform is turned into the boundary problem of one-dimensional discrete wavelet transform, which not only greatly reduces the boundary distortion area, improves the precision of reconstructed DEM data near the boundary, but also decreases the number of zeros adding on the boundary for wavelet transform, and boosts the compression ratio. On the basis of analyzing the distribution characteristics of coefficients in low and high frequency bands, a mixed entropy coding plan is applied, and a high efficient quantizator called"self-adaptive hard threshold"is established, which is helpful for improving the precision of the reconstructed DEM data and for enhancing compression ratio.

交织编码在3G系统中已经大量使用，数据通过卷积编码后进行分组交织，在接收端完成反交织，将连续误码分散成非连续误码，从而使得误码在纠错允许的范围内得到纠正； CPLD 具有方便的在线编程功能，可以用来实现交织编码；考虑到矩阵交织器的多样性而设计的通用矩阵交织器，只须通过修改一些参数值即可实现不同的交织器，大大节省了设计时间。
