Patent ID: 8401125

Claim:
A receiving apparatus that receives signals in a wireless communication system, in which the signals include a dedicated channel estimation sequence having a first and a second dedicated channel estimation sequence, the apparatus comprising: an analog to digital converter that converts received signals to digital samples with a sampling rate identical to a symbol rate of the received signals; a channel estimation unit that performs a channel estimation based on the first and second dedicated channel estimation sequences included in the digital samples of the received signals; an evaluation unit that evaluates a channel estimation result from the channel estimation unit; and a control unit that controls a phase of the sampling rate of the analog to digital converter so that the analog to digital converter converts the first dedicated channel estimation sequence with a sampling clock having a first phase and the second dedicated channel estimation sequence with the sampling clock having a second phase, the first phase being different from said second phase, wherein the evaluation unit detects which of the first or the second dedicated channel estimation sequence has the best quality, and the control unit sets the phase of the sampling clock of the analog to digital converter based on the evaluation of the channel estimation result to the same phase which was used to analog to digital convert the dedicated channel estimation sequence with the best quality.
