| Abstract: | 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 ... |
