Abstract:
1. An information detection method for a High Speed Downlink Shared Control Channel (HS-SCCH), comprising: rate de-matching a front detection signal of a first part control information of each HS-SCCH in a HS-SCCH monitor set, obtaining a piece of rate de-matched information corresponding to the front detection signal of each HS-SCCH monitor channel; removing a user mask for each rate de-matched information; Viterbi decoding each rate de-matched information of which the user mask is removed, obtaining Viterbi-decoding 0 state accumulated metric corresponding to the front detection signal of each HS-SCCH monitor channel, and summing an absolute value of soft information of each HS-SCCH information respectively, with the absolute value of the soft information being obtained by removing the user mask; and obtaining determination variables of each HS-SCCH, according to the Viterbi 0 state accumulated metric corresponding to the front detection signal of each HS-SCCH and the sum of absolute values of the corresponding soft information; selecting a maximum from the obtained determination variables of HS-SCCH, comparing the maximum with the preset threshold, and determining whether the HS-SCCH of this user is detected.
