Abstract:
InM SK modu lation, due to the d iscontinuous slope dur ing the sw itch tim e of the phasic path, the dropp ing veloc ity o f them odu la tion spectrum is a ffected, and IJF-OQPSK is introduced to solve the lim itation, sm ooth the phasic path and im prove the spec trum. This pape rm akes a com par ison betw een both the m odulations and introduces a new m odulation nam ed IJF-MSK, that is, code the dig ita l base-band signa lw ith IJF, then modu late it w ithM SK. The simu lation proves that com pared w ithMSK and IJF-OQPSK, it has a better spectrum, the dropping ve locity of the secondary pe tal is low er than 20 dB.
