| Abstract: | The modulation of FQPSK is proposed for the request of both high spectrum efficiency and high power efficien- cy.The technical principle of the modulation system was analyzed in this paper.And based on the principle,the paper simulated the modulation of FQPSK which using the principle of trellis-coded orthogonal modulation to realize the arith- metic of cross-correlation.Then the performance of the modulation was analyzed according to the results of simulation. |
