Based on the error rates evaluated,the hopping frequences with good performances can be adaptively selected. The paper gives out theory provements, realizing meathods and Computer Simulation results of the Pseudo error measurment. 短波 慢跳频 自适应选频 short wave slow frequence hopping adaptive selecting frequency O451 国家自然科学基金,国防预研基金 1997-01-01 2021-04-01 1
