A Non-Gaussianity-Aware Receiver for Impulsive Noise Mitigation in Underwater Communications.

Publication Type:Academic Journal

Source(s):IEEE Transactions on Vehicular Technology. Jun2021, Vol. 70 Issue 6, p6018-6028. 11p.

Abstract:Impulsive noise significantly deteriorates the performance of orthogonal frequency-division multiplexing (OFDM)-based underwater acoustic (UWA) communication systems. The pulse blanking (PB) based approach can mitigate the impulsive noise. However, it ...

Adaptive Turbo Equalization for Differential OFDM Systems in Underwater Acoustic Communications.

Publication Type:Academic Journal

Source(s):IEEE Transactions on Vehicular Technology. Nov2020, Vol. 69 Issue 11, p13937-13941. 5p.

Abstract:In this correspondence paper, an adaptive turbo equalizer for differential OFDM systems in underwater acoustic communications is proposed. This scheme first reconstructs the demodulation symbols using the soft information fed back from the channel deco...

A Speed Adaptive Joint Subcarrier and Power Allocation Technique for Downlink OFDMA Video Transmission Over Doubly Selective Channels.

Publication Type:Academic Journal

Source(s):IEEE Transactions on Vehicular Technology. Feb2020, Vol. 69 Issue 2, p1879-1887. 9p.

Abstract:In this paper we propose a quality of experience (QoE) based joint subcarrier and power allocation (JSPA) technique for orthogonal frequency division multiple access (OFDMA) based downlink video transmission over doubly selective channels (DSCs), where...

Power Multiplexing NOMA and Bandwidth Compression for Satellite-Terrestrial Networks.

Publication Type:Academic Journal

Source(s):IEEE Transactions on Vehicular Technology. Nov2019, Vol. 68 Issue 11, p11107-11117. 11p.

Abstract:Due to the spectrum scarcity in the space information networks, non-orthogonal multiple access (NOMA) is envisioned as a promising technique in satellite-terrestrial communications networks as its improved system capacity and spectral efficiency. In th...

Priori-Aided Detection for Generalized Space-and-Frequency Index Modulation Systems With Multi-Carrier Frequency Offset.

Publication Type:Academic Journal

Source(s):IEEE Transactions on Vehicular Technology. Oct2019, Vol. 68 Issue 10, p10330-10334. 5p.

Abstract:In this paper, two priori-aided detectors are proposed for generalized space-and-frequency index modulation (GSFIM) systems with the objective of mitigating the effect of the multi-carrier frequency offset (CFO). Specifically, based on the priori infor...

Carrier Frequency Offset Estimation in Uplink OFDMA Systems: An Approach Relying on Sparse Recovery.

Publication Type:Academic Journal

Source(s):IEEE Transactions on Vehicular Technology. Oct2017, Vol. 66 Issue 10, p9592-9597. 6p.

Abstract:This paper proposes a novel blind carrier frequency offset (CFO) estimator, namely the sparse recovery assisted CFO (SR-CFO) estimator, for the uplink orthogonal frequency-division multiple access (OFDMA) systems. By exploiting the sparsity embedded in...

Joint Load Balancing of Downlink and Uplink for eICIC in Heterogeneous Network.

Publication Type:Academic Journal

Source(s):IEEE Transactions on Vehicular Technology. Jul2017, Vol. 66 Issue 7, p6388-6398. 11p.

Abstract:The 3GPP has proposed enhanced intercell interference coordination (eICIC) by making the macrocell silent in the almost blank subframes (ABSs) to mitigate interference for low-power base stations (BSs) in the downlink direction. However, two important ...

Spectrally Precoded OFDM Without Guard Insertion.

Publication Type:Academic Journal

Source(s):IEEE Transactions on Vehicular Technology. Jan2017, Vol. 66 Issue 1, p107-121. 15p.

Abstract:Orthogonal frequency-division multiplexing (OFDM) signaling format is commonly associated with guard subintervals to reject interblock interference (IBI) and enable simple one-tap frequency-domain equalization (FDE) at the receiver when received over d...

Symbol Cyclic-Shift Equalization Algorithm—A CP-Free OFDM/OFDMA System Design.

Publication Type:Academic Journal

Source(s):IEEE Transactions on Vehicular Technology. Jan2017, Vol. 66 Issue 1, p282-294. 13p.

Abstract:The use of cyclic prefix (CP) allows all existing orthogonal frequency-division multiplexing or multiple access (OFDM/OFDMA) systems to realize high-data-rate transmission in frequency-selective fading channels at the expense of losses in spectrum effi...

OFDM Receiver for Fast Time-Varying Channels Using Block-Sparse Bayesian Learning.

Publication Type:Academic Journal

Source(s):IEEE Transactions on Vehicular Technology. Dec2016, Vol. 65 Issue 12, p10053-10057. 5p.

Abstract:We propose an iterative algorithm for orthogonal frequency-division multiplexing (OFDM) receivers operating over fast time-varying channels. The design relies on the assumptions that the channel response can be characterized by a few nonnegligible sepa...
