tailieunhanh - Mutual Interference In Fast-frequency-hopped, Multiple-frequency-shift-keyed, Spread-spectrum Communication Satellite Systems

This report presents the results of a theoretical analysis of a frequency-hopping, multiple-frequency-shift-keyed, spread-spectrum communication system using a nonprocessing communication satellite transponder. A large number of users are assumed to be hopping pseudo-randomly about the transponder passband in time synchronization and approximate frequency synchronization. The users are assumed to | RAND Mutual Interference in Fast-Frequency-Hopped Multiple-Frequency-Shift-Keyed Spread-Spectrum Communication Satellite Systems Edward Bedrosian Project AIR FORCE Arroyo Center The research described in this report was sponsored jointly by the United States Air Force Contract F49620-91-C-0003 and by the United States Army Contract No. MDA903-91-C-0006.
