Summary

Summary. Direct-sequence MPSK and Frequency-hop MFSK represent two principle categories of spread-spectrum communications. Another technique is time-hope PPM, may be popular in the future. They rely on the use of a pseudo-noise (PN) sequence, which is applied differently in these categories.
