Single tone interference rejection of code-phase multiplexed direct-sequence spread-spectrum signaling
A.Y.-C. Wong, Victor C. M. Leung · IEEE Transactions on Communications · 1996
This paper presents the code-phase multiplexed direct-sequence spread spectrum signaling system, which employs parallel transmissions of several data streams modulated by different phase shifts of the same pseudo-noise (PN) code. System performance against single tone jammers is analyzed. Theoretical and simulation results are presented to show that the design increases the processing gain without reducing the data rate.
