Ayc. Wong et Vcm. Leung, SINGLE TONE INTERFERENCE REJECTION OF CODE-PHASE MULTIPLEXED DIRECT-SEQUENCE SPREAD-SPECTRUM SIGNALING, IEEE transactions on communications, 44(5), 1996, pp. 557-561
This paper presents the code-phase multiplexed direct-sequence spread
spectrum signaling system, which employs parallel transmissions of sev
eral data streams modulated by different phase shifts of the same pseu
do-noise (PN) code. System performance against single tone jammers is
analyzed. Theoretical and simulation results are presented to show tha
t the design increases the processing gain without reducing the data r
ate.
