Single-carrier frequency division multiple access (SC-FDMA) has appeared to be a promising technique for high data rate uplink communications. Aimed at SC-FDMA applications, a cyclic prefixed version of the offset quadrature amplitude modulation based OFDM (OQAM-OFDM) is first proposed in this paper. We show that cyclic prefixed OQAM-OFDM (CP-OQAM-OFDM) can be realized within the framework of the...
In this paper, we devise a frequency-interleaved (FI) discrete Fourier transform (DFT) spread orthogonal frequency-division multiplexing (OFDM), or simply FI-DFTS-OFDM, transmission scheme with an iterative receiver. The system is indeed the conventional DFTS-OFDM scheme with a frequency-domain interleaver, from which a significant reduction in the bit-error-rate (BER) performance can be obtained...
In this paper, we present the link level performance of SC-FDMA with SDMA (Space Division Multiple Access), real channel estimation and low complexity frequency-domain turbo equalization. We give the implementation of the minimum-mean-squared-error based turbo equalization which is suitable for DFT-S-OFDM based SDMA systems. The block error rate performance of SC-FDMA and OFDMA with SDMA and turbo...
