“…Expectation propagation has been used in frequency domain in [36], [37] mainly for the mitigation of inter-band interference. The former reference uses it for a generalized frequency division multiplexing receiver, as an iterative block receiver, with cubic complexity in block length, and with a single self-iteration.…”

“…The former reference uses it for a generalized frequency division multiplexing receiver, as an iterative block receiver, with cubic complexity in block length, and with a single self-iteration. That structure is extended for SC-FDMA in [37] under the acronym of joint-EP (J-EP). The latter reference also includes a single-tap simplification of that receiver, denoted distributed-EP (D-EP), which was however obtained through a zero-forcing type derivation, which makes it severely vulnerable to spectral nulls [37, eq.…”

“…There are numerous emerging EP-based receivers in the literature, as stressed in the introduction, and in this sec-tion the proposed FDE is compared with self-iterated timedomain block (SIBLE-EPIC, denoted nuBEP in [29]) and filter (SIFLE-EPIC, denoted EP-F in [29]) receivers and to the single-tap FD receiver, D-EP, in [37]. The proposed receiver is not compared to the exact FD receiver, J-EP in [36], [37], as it is equivalent to the SIBLE-EPIC with a single SI, without damping, making it sub-optimal compared to the SIBLE-EPIC. The block receiver in [28], is neither included in the comparison, as it is a sub-optimal block receiver which ignores prior information from the decoder at each SI (but a comparison is available in [31]).…”

An original expectation propagation (EP) based message passing framework is introduced, wherein transmitted symbols are considered to belong to the multivariate white Gaussian distribution family. This approach allows deriving a novel class of single-tap frequency domain (FD) receivers with a quasi-linear computational complexity in block length, thanks to Fast-Fourier transform (FFT) based implementation. This framework is exposed in detail, through the design of a novel double-loop single-carrier frequency domain equalizer (SC-FDE), where self-iterations of the equalizer with the demapper, and turbo iterations with the decoder, provide numerous combinations for the performance and complexity trade-off. Furthermore, the flexibility of this framework is illustrated with the derivation of an overlap FDE, used for time-varying channel equalization, among others, and with the design of a FD multiple-input multiple-output (MIMO) detector, used for spatial multiplexing. Through these different receiver design problems, this framework is shown to improve the mitigation of inter-symbol, inter-block and multi-antenna interferences, compared to alternative singletap FD structures of previous works. Thanks to finite-length and asymptotic analysis, supported by numerical results, the improvement brought by the proposed structures is assessed, and then completed by also accounting for computational costs.

“…These equations have similar expressions with previous work on EP [13], [14], [19], as any other linear estimation model would do so, but underlying problems are quite different. As far as we know, none of the prior work on EP studied non-orthogonal FD MUD where same frequency and time resources are shared.…”

“…Previous works designing iterative receivers inside the EP framework showed both impressive and close to capacity performance [13]- [15], [18]. However its usage in FD remains limited, [19], with either excessive complexity, or high sensitivity to spectral nulls. This paper addresses the derivation of low-complexity MUD for non-orthogonal multiple-access in the presence of ISI and MAI.…”

A novel multiuser multiple-input multipleoutput (MU-MIMO) receiver for single-carrier frequencydivision multiple-access (SC-FDMA) is proposed within the expectation propagation (EP) framework. Recent advances in iterative receiver design show the ability of low complexity EP-based iterative algorithms to achieve performance close to maximum a posteriori (MAP) detection. In this paper, based on the exact derivation of frequency-domain EP-based turbo receivers, we propose a novel spectrally and computationally efficient soft interference canceller (IC) with a doubly-iterative architecture. Asymptotic and finite-length analysis show that our proposal outperforms existing schemes with comparable complexity, in various spatial-multiplexing configurations.
