| Abstract: |
| In order to improve the acquisition performance of spread spectrum sys
tem, there are two ways that are improving the PN code acquisition precisi
on or using the architecture of multiple PN code loop in the receiver. In this p
aper, a
design method of multiple PN code loops which are applied to spread spectrum rec
eiver is introduced. With this method, the acquisition circuit can be simplified
, the accur
acy requirement of the loop can be reduced and the resource consumption is reduc
ed by
50%, but the performance of the system will be improved exponentially. |
