Abstract
A Method for estimating the channel in a Long Term Evolution (LTE) communication system, said method involving the step of extracting a Primary Synchronization Signal (PSS) from a received signal and further involving the step of spanning said PSS based Least Square (LS) channel estimation on the 64 sub-carriers so as to facilitate the MMSE channel estimation. Preferably, the spanning is performed by means of an interpolation of the particular sub-carriers which are not allocated to said PSS (#-32, d.c.) The method involves the steps of: —Perform LS channel estimation on the 62 sub-carriers containing the PSS () —reconstruct the LS channel estimation on the 64 central sub-carriers by interpolating () on subcarriers not allocated to said PSS; —Apply () an Inverse DFT or Inverse Fast Fourrier Transform —Extract () the L first samples, with L corresponding to the length of the channel; —multiply () by (FF+σC)—Zero-pad () the resulting signal to length 64; —Apply () a DFT or an FFT.
