The present invention discloses a matched filtering circuit apparatus in the baseband processing system of the terminal device and method thereof. The circuit apparatus comprises a control unit for controlling the processing procedures of de-scrambling, de-spreading, de-rotating and maximal ratio combining data, the output ports of the control unit connects with a V vector buffer unit, a shift integral selection unit and a coherent integral unit for implementing the matched filtering and data buffer. Due to the application of entirely pipeline design structure, the processes of data buffer and matched filtering can be carried out simultaneously, thus shortening time consumption of the terminal hardware accelerator and effectively improving the operation efficiency of the mobile communication terminal hardware system; Moreover, according to practical needs, the size of the shift register group in the shift buffer selection unit and the number of correlators in the correlator unit can be adjusted to make it compatible with matched filtering algorithms in various application environments. The present invention has simple control logic and is easy to implement, thus it has very strong universality and practicability. |
