Image Number 5 for United States Patent #6768769.
A finger receiver has a data decision unit for deciding whether there is received data or not. If the data decision unit determines that there is received data, then a symbol data selector outputs, to a circuit at a later stage, accumulated and added symbol data at one of complex-inverse diffusing points in a plurality of phases, which is detected as having a maximum accumulated slot power value by a maximum value detector. If the data decision unit determines that there is no received data, then the symbol data selector outputs, to the circuit at the later stage, accumulated and added symbol data at the same point as the accumulated and added symbol data outputted in a preceding slot.
