Abstract
A fraction chip correlation device for a spread spectrum receiver for receiving signals modulated with spread spectrum codes and a method for operating fractional chip correlation to spread spectrum signals received by the spread spectrum receiver are disclosed. In the present invention, at least one delayed version of an input signal is generated to be correlated with a local code replica to accomplish fractional chip correlation. By doing so, correlators can operate at a low speed, so that power consumption of the receiver can be significantly reduced.
