ABSTRACT:
A method (400) and a receiving unit (220) for demodulating a multi-path signal are described herein. The receiving unit (220) may be configured to receive the multi-path signal. The receiving unit (220) may include an input buffer controller (305), an input buffer (310), a rake finger (330), and a sum generator (340). The input buffer (310) may be configured to store data samples associated with a plurality of paths of the multi-path signal. The input buffer controller (305) may be configured to time-align the data samples relative to each other, and to delay the data samples. The rake finger (330) may be configured to de-spread and to accumulate the delayed data samples for a sub-correlation length. The sum generator (340) may be configured to combine a plurality of outputs from the rake finger (330). Each of the plurality of outputs corresponds to one of the plurality of paths of the multi-path signal.
