<p>A signal to interference ratio (SIR) detecting method is used to carry out an E- DPCCH SIR detection in a HSUPA system and a HS-DPCCH SIR detection in a HSDPA system. The method includes: at first acquiring the noise energy of each DPCCH symbol and the noise energy of each E-DPCCH/HS-DPCCH symbol, then carring out channel estimate for E-DPCCH/HS-DPCCH, obtaining signal output sequence of E-DPCCH/HS-DPCCH, carring out the correlation operation for the output sequence of E-DPCCH or cumulative mean operate for the output sequence of HS-DPCCH, and obtaining SIR of E- DPCCH/HS-DPCCH.</p> |
