Abstract

A subband coding algorithm is designed for compression of wideband RF data and eventual implementation on a reconfigurable computer board. The algorithm involves a multirate filter bank, adaptive uniform scalar quantization, and Huffman entropy coding. We report the performance of the algorithm in software on RF data from the DOE satellites ALEXIS and FORTE. A reconfigurable computer array board, RCA-2, designed and assembled at LANL is presented as a target platform for hardware implementation of the algorithm
