The above system model is used to perform the simulation. We evaluate the proposed method in this section based on the two contents mentioned in the Purpose slide. Part 1 is the interference reduction. We compare the PDMA scheme with and without DSSS and verify the relationship between peak power and reception quality. Part 2 is the spectral efficiency. We examine the relationship between spectral efficiency when the number of users is increased, and compare DSSS-PDMA with existing schemes such as NOMA and OMA.
