摘要：
OQPSK is the one kind of improved QPSK. QPSK can produce the phase ambiguity in carrier recovery process. OQPSK eliminates the influence of phase ambiguity, on the correct decision. For the requirement of designing the digital modulation of satellite signal simulator channel, the article proposes the proposal to realize the OQPSK by selecting Xilinx Corporation Spartan3 series XC3S4000. This design combines the VerilogHDL hardware description language with the schematic diagram. union design method, has the very strong versatility and the very good probability. The test result indicates this plan has achieved the anticipated goal.
