An integrated circuit comprises channel estimation module for generating at least one channel estimation signal based on at least one of a plurality of pilot signals within concurrent resource elements. The channel estimation module comprising extension module arranged to receive a demodulation reference signal comprises the plurality of pilot signals and to add an extension to the demodulation reference signal, inverse discrete Fourier transform (IDFT) module arranged to perform an inverse discrete Fourier transform function on the extended demodulation reference signal to generate a time domain reference signal, reference signal separation module arranged to separate out at least one pilot signal component from the time domain reference signal. The channel estimation module further comprises and discrete Fourier transform (DFT) module arranged to perform a discrete Fourier transform function on the at least one pilot signal component to generate at least one extended channel estimation signal. |
