The multiplex system based on m_W sequences uses m_W sequences as the interior sequences,but the sensitivity of m_W sequences to system synchronization precision degrades the performance of multi-path interference(MPI) suppression.This paper introduces two improved multiplex systems which use modified complete complementary series(MCCS) and complete complementary series(CCS) as their interior sequences respectively.Due to the perfect correlation performance of MCCS and CCS,these improved multiplex systems more effectively suppress MPI in systems.The simulation was executed and the parameter named reciprocal-gain was used to evaluate the performance of the improved multiplex systems.Experimental data proves that the multiplex system based on MCCS effectively suppresses PMI.
