Method and system for delay locked loop for rake receiver

A method comprising:

• receiving, in a delay locked loop (DLL), first and second signals from first and second channels respectively;
• descrambling, in the DLL, the first and second signals to provide first and second descrambled signals respectively;
• accumulating, in the DLL, the first and second descrambled signals to provide first and second accumulated signals respectively;
• calculating, in the DLL, first and second signal powers associated with the first and second accumulated signals respectively;
• calculating, in the DLL, a difference between the first and second signal powers;
• and
• comparing, in the DLL, the difference with a threshold value, and providing a signal to adjust a sampling time associated with a data channel and at least one of the first and second channels based on a result of the comparing.

A rake receiver comprising:

• first and second front-ends configured to respectively receive first and second signals from first and second channels, wherein the second signal is delayed with respect to the first signal by a predetermined time;
• first and second descramblers configured to respectively descramble the first and second signals to provide first and second descrambled signals, wherein the first descrambler is configured to multiply descrambled data included in the first signal with a spreading code to despread the descrambled data;
• first and second accumulators configured to respectively accumulate the first and second descrambled signals to provide first and second accumulated signals;
• first and second power blocks configured to respectively calculate first and second signal powers associated with the first and second accumulated signals;
• a difference block configured to calculate a difference between the first and second signal powers;
• and
• a comparator configured to compare the difference with a threshold value, and to provide a control signal to adjust a sampling time associated with a data channel and at least one of the first and second channels based on a result of the comparison.
