Method and apparatus for code identification in wireless applications |
摘要 |
A system and method are provided for determining whether a chipping code from a group of codes is used in a signal. In one embodiment of the invention, a signal is received and each code from the group is correlated with the received signal. The ratio of the highest correlation value to the second highest correlation value is calculated. If the ratio exceeds a threshold, the chipping code may be determined as the chipping code used in the signal. In another embodiment, the ratio of the highest correlation value and the total received power of the signal is calculated. If the ratio exceeds a threshold, the chipping code may be determined as the chipping code used in the signal.
