Patent ID: 8526548

Claim:
A matched filtering circuit apparatus in a baseband processing system of a terminal device, the matched filtering circuit apparatus being located in a joint detection circuit in said baseband processing system, and said matched filtering circuit apparatus comprising a control unit, a V vector buffer unit, a shift integral selection unit, a correlator unit, as well as a coherent integral unit, wherein, said control unit is configured to control processes of de-scrambling, de-spreading, de-rotating and maximum ratio combining data; an output port of said control unit connects to said V vector buffer unit, said shift integral selection unit and said coherent integral unit simultaneously; said V vector buffer unit is configured to perform data buffering when the matched filtering circuit apparatus performs matched filtering operations; a front end of said coherent integral unit connects to the correlator unit, and also connects to said V vector buffer unit and said shift integral selection unit through said correlator unit; and said correlator unit is configured to perform correlated processing for parallel data and perform a summation operation on correlated processing results.
