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