Abstract:
1. A receiving apparatus for receiving signals in a wireless communication system, in which the signals comprise a dedicated channel estimation sequence, the receiving apparatus comprising: a channel estimation unit configured to perform a channel estimation on the dedicated channel estimation sequence comprised in a received signal; a peak detection unit configured to detect a complex sample having the highest power level of complex samples of the channel estimation result as a peak complex sample; a noise reduction unit configured to reduce noise in the channel estimation result obtained from the channel estimation unit by setting complex samples of the channel estimation result which are below a noise threshold to zero; a windowing unit configured to arrange the noise reduced channel estimation result in a window having a preset number of complex samples by determining the number of useful complex samples before and after the peak complex sample and setting the remaining complex samples to zero; and a frequency domain equalizing unit configured to perform an equalization on the received signal in frequency domain on the basis of the windowing unit.
