“…Thus, the formulation of the received signal in Equation 10, leading to the PARAFAC model, also allows us to design a time-domain CFO compensation scheme for data symbols using Equations 22 and 21. The CFO compensation scheme in [29] also formulates the received periodic signal in interleaved OFDMA transmissions as a low-dimensional matrix form similar to Y(q) for CFO compensation. However, the scheme in [29] is based on OFDMA transmissions, and thus, the scheme in [29] is not directly applicable to SC-FDMA transmissions.…”

“…In addition to CFO estimation, various CFO compensation algorithms have also been proposed in the literature [24][25][26][27][28][29]. An interference cancelation scheme based on circular convolution is proposed in [24] while parallel interference cancelation is used in [25] for CFO compensation.…”

Frequency synchronization is a critical requirement for single-carrier frequency division multiple-access (SC-FDMA) uplink transmissions. Based on the key observation that the received signal at the base station can be formulated as the parallel factor analysis model, we present a joint carrier frequency offset (CFO) estimation and compensation scheme for SC-FDMA uplink transmissions with interleaved sub-carrier allocation. The proposed scheme, employing identical training symbols, guarantees the identifiability of CFO estimation, allows the system to operate on full load, and it is readily extendible to multi-antenna base station (BS) reception. Comparisons with existing approaches in the literature reveal that the proposed algorithms provide lower complexity and superior performance.
