Abstract
SC modulation (Single-Carrier) with FDE (Frequency-Domain Equalization) allows
excellent performance in severely time-dispersive channels, provided that accurate channel estimates
are available at the receiver. For this purpose, pilot symbols and/or training sequences are usually
multiplexed with data symbols, which lead to spectral degradation. As an alternative, we can use
implicit pilots (i.e., pilots superimposed to data).
In this paper we consider MIMO SC-FDE systems where the channel estimation is based on either
multiplexed (explicit) or implicit pilots, for comparison purposes. An iterative receiver with joint
equalization, turbo decoding and channel estimation was employed in order to optimize the results,
and to reduce the high interference levels between data and pilots (for the implicit pilots). The main
differences between the different schemes are discussed and the performance results show that the
proposed techniques for channel estimation yield excellent results.
