In order to evaluate the performance of the new dynamic spectrum anti-jamming (DSAJ) system in anti-jamming communications
channel capacity and bit error rate (BER) of DSAJ systems under partial-band noise jamming are studied via theoretical analysis and simulations.Capacity and BER of both DSAJ systems and conventional frequency hopping (FH) systems are compared.Results show that within a wide range of partial-band jamming factor values
DSAJ systems achieve larger capacity than FH systems.Even without jammer state information (JSI)
DSAJ systems still achieve larger capacity than FH systems with JSI.At medium to high signal-to-jamming ratios (SJR)
DSAJ systems achieve smaller BER than FH systems under worst-case partial-band jamming.Moreover
error correction coding can further improve the performance of DSAJ systems.
