Patent ID: 7586975

Claim:
A method for receiving multi-path signals in a communication system, the method comprising steps of: calculating a fast path correlation value from a first path signal being faster than an allocated multi-path signal; calculating a slow path correlation value from a second path signal being slower than the allocated multi-path signal; obtaining information regarding timing of the allocated multi-path signal by using the fast path correlation value and the slow path correlation value; and receiving the allocated multi-path signal based on the obtained timing information; wherein the step of calculating the fast path correlation value comprises steps of: finding a first correlation value, the first correlation value being obtained through correlation between a predetermined signal and the first path signal; finding a third correlation value, the third correlation value being obtained through correlation between the predetermined signal and a third path signal, the third path signal being faster than the first path signal; and subtracting the third correlation value from the first correlation value; wherein the step of calculating the slow path correlation value comprises steps of: finding a second correlation value, the second correlation value being obtained through correlation between the predetermined signal and the second path signal; finding a fourth correlation value, the fourth correlation value being obtained through correlation between the predetermined signal and a fourth path signal, the fourth oath signal being slower than the second path signal; and subtracting the fourth correlation value from the second correlation value.
