CHANNEL GAIN ESTIMATION IN A RAKE RECEIVER USING COMPLEX WEIGHT GENERATION (CWG) ALGORITHMS

摘要

A CHANNEL ESTIMATION METHOD WHICH REDUCES THE STRAIN ON RESOURCES OF A RAKE RECEIVER USING A COMPLEX WEIGHT GAIN ( CWG ) ALGORITHM. IN ONE EMBODIMENT, A NON-ADAPTIVE ALGORITHM IS USED TO AVERAGE BLOCKS OF PILOT SYMBOLS FROM SEVERAL SLOTS. IN ANOTHER EMBODIMENT, AN ADAPTIVE ALGORITHM IMPLEMENTS SLIDING WINDOW AVERAGING OR A RECURSIVE FILTER. USING A CWG ALGORITHM REDUCES THE MEMORY AND PROCESSOR REQUIREMENTS OF THE RAKE RECEIVER.(FIG 3B)
