CPC classification number: H04L1/0059 , H04L1/0055 , H04L1/0072
Abstract: Method for blindly detecting a channel:, like e.g. a HSDPA high speed shared control channel, possibly intended for a designated user equipment among n channels (HS-SCCH1,...,HS-SCCHn) received in parallel by said designated user equipment during a given duration, each channel (HS-SCCH1,...,HS-SCCHn) received during said duration carrying encoded data masked with an identifier associated to a user equipment. The method comprises a selecting phase comprising a demasking step demasking the received masked encoded data of each channel with the identifier of said designated user equipment, a decoding step decoding the demasked encoded data of each channel to obtain a set of digital decoded data for each channel, a calculating step calculating, from each set of digital decoded data, a global information representative of a confidence in digital data received on the physical channel, and a detecting step detecting said channel using said global information.
