HF Programmable Modem.
Abstract
This is the final report of a seven-month program beginning April 15, 1974 and ending approximately October 15, 1974 to design and fabricate two programmable signal processors with the necessary software to provide for real time operation of specific High Frequency Modem configuration. These configurations include: (a) Convential time-differential phase shift keyed modulation (TDPSK). (b) DEFT mode, using frequency differential phase shift keyed modulation (FDPSK). (c) CODEM mode, combined TDPSK with coding for error control and the use of soft decision decoding.
