Abstract
This letter investigates the frequency domain pilot multiplexing technique (FDPMT) for channel estimation of single-carrier frequency domain equalization (SC-FDE) and proposes a simple pilot position detection technique to blindly estimate the pilot positions in the frequency domain by using the noise subspace. Simulation results show that the proposed technique is robust to multipath fading channels with exponential power delay profile.
