Abstract:

Conventional SC (single-carrier) modulations have been shown to be suitable for block transmission schemes with cyclic prefix. When selected for broadband wireless communication systems, they allow better performances than the corresponding OFDM-based (orthogonal frequency division multiplexing) block transmission schemes, while also offering a low complexity of implementation. In this paper, we propose an extension of the recently developed IB-DFE concept (iterative block decision feedback equalization), for SC-based block transmission, so that it can be adopted within transmit/receive space diversity implementations. The particular case where only one iteration is employed corresponds to a conventional, linear FDE scheme (frequency domain equalization); the subsequent iterations with the IB-DFE scheme are shown to provide increasingly improved performances.
