The utility model provides a new-type Finger message way estimator with high reliability, low complexity and anti jamming. Utilizing a time in-phase pilot I /Q symbolic sequence demodulated by a Finger random sequence descrambling unit, making a single pole IIR filtering towards the time in-phase pilot I /Q symbolic sequence, the Finger message way estimator can get a weight coefficient which completes weight towards each orthogonal code way (transferring control information and operation information) data sequence demodulated and outputted (resumed) by the Finger. After the weight towards each (resumed control information and operation information data sequence) demodulated and outputted by the Finger is completed, for each code way, all the output result (the orthogonal despread data sequence after weight) of relative Finger demodulation unit combine in a phase rotation combiner of the code way. The Finger message way estimator adopting an exponential window IIR filter to filter the time in-phase pilot I /Q symbolic sequence improves the veracity and the reliability of the Finger message way estimator, which is fit for being embedded in communication chips and being realized in the form of hardware. The utility model can be used directly in the business.
