Compression algorithm for data analysis in a radio link (preparation of PACEM 2 experiment)
Abstract
The Hadamard transformation for image compression is applied to a radio data transmission system. The programs used and the performance obtained are described. The algorithms use PASCAL and the listed programs are written in FORTRAN 77. The experimental results of 62 images of 64 lines, show a standard deviation of 1.5% with a compression rate of 18.5, which is in accordance with the proposed goals.
