Accurate Analysis of Processing Gain in Direct Sequence Spread Spectrum Communication Systems under Single-tone and Narrowband Interference
Hu Luo · Telecommunication Engineering · 2014
The accurate formulas of processing gain are theoretically derived under single-tone interference and narrowband interference in direct sequence spread spectrum(DSSS) communication systems.Moreover,the numerical simulation of derived formulas is performed.The numerical results show that the single-tone interference capability depends on the relative location of carrier frequency between the single-tone interference and the spread spectrum system,and the narrowband interference capability depends on the relative location of carrier frequency and the interference bandwidth.The conclusions provide reference for the design of DSSS communication systems.
