Optimized method of generating the spread-spectrum sequences based on Logistic-map
Based on the Logistic-map,an optimized method of generating the spread-spectrum sequences was proposed.An initial value was given and iterated in the Logistic map,then L bit qualification was done to every point,in this way,new spread spectrum sequence would be achieved by shorten.It was compared wi...

| description | Based on the Logistic-map,an optimized method of generating the spread-spectrum sequences was proposed.An initial value was given and iterated in the Logistic map,then L bit qualification was done to every point,in this way,new spread spectrum sequence would be achieved by shorten.It was compared with conventional chaotic code and Gold code and finally simulated in the DS-CDMA systems.Experiment results show that the iterative times are reduced,the calculating speed is improved,the spread-spectrum sequences can be reshaped with any length and the number of these sequences is larger than Gold sequence in being.The best quantification order is got too. |
