Compression of Wideband RF Signals
Objective: Research on new compression algorithms for wide-band RF data and implementation on reconfigurable hardware.
Accomplishments: Demonstration of experimental algorithms on Blackbeard and FORTE signals; analysis of rate-distortion characteristics and effects of data quantization on exploitability.
Future goals: Optimize performance for specific communication and exploitation needs; assist with reconfigurable hardware implementation; integrate compression and error control coding.
Developers: Chris Brislawn (CIC-3), Shane Crockett (student, USNA).
Example: spectrogram of FORTE data (L); after 4:1 compression (R).
