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...

Mitigation of Uplink ICI and IBI in OFDMA Two-Tier Networks.

Publication Type: Academic Journal

Source(s): IEEE Transactions on Vehicular Technology. Aug2016, Vol. 65 Issue 8, p6244-6258. 15p.

Abstract: For two-tier networks using orthogonal frequency-division multiple access (OFDMA) over frequency-selective channels, macrocell-user (MU) signals generally arrive at small-cell base stations (SBSs) with different delays and can hardly be synchronized in...

Correlatively Precoded OFDM With Reduced PAPR.

Publication Type: Academic Journal

Source(s): IEEE Transactions on Vehicular Technology. Mar2016, Vol. 65 Issue 3, p1409-1419. 11p.

Abstract: Correlative precoders have been proposed for orthogonal frequency-division multiplexing (OFDM) to provide either improved spectral sidelobe suppression, which yields very compact signal spectrum, or enhanced intercarrier interference (ICI) self-cancela...

On the Banded Approximation of the Channel Matrix for Mobile OFDM Systems.

Publication Type: Academic Journal

Source(s): IEEE Transactions on Vehicular Technology. Aug2015, Vol. 64 Issue 8, p3526-3535. 10p.

Abstract: In mobile orthogonal frequency-division multiplexing (OFDM) systems, a frequency-domain channel matrix represents the same-carrier channel frequency response in the diagonal and intercarrier interference (ICI) between the subcarriers in the off-diagona...

Low-Complexity ICI Reduction Method for OFDM Systems With Large Subcarrier Numbers.

Publication Type: Academic Journal

Source(s): IEEE Transactions on Vehicular Technology. Aug2015, Vol. 64 Issue 8, p3505-3512. 8p.

Abstract: The intercarrier interference (ICI) resulting from the loss of orthogonality caused by the time-varying property of the propagation channels degrades the data detection performance of orthogonal frequency-division multiplexing (OFDM)-based wireless com...

Analysis of Uplink Intercarrier Interference in OFDMA Femtocell Networks.

Publication Type: Academic Journal

Source(s): IEEE Transactions on Vehicular Technology. Mar2015, Vol. 64 Issue 3, p998-1013. 16p.

Abstract: The femtocell has been considered to be a promising and cost-effective technology to enhance cellular coverage and capacity. However, in the uplink of orthogonal frequency-division multiple access (OFDMA)-based femtocell systems, the signals from macro...

FADAC-OFDM: Frequency-Asynchronous Distributed Alamouti-Coded OFDM.

Publication Type: Academic Journal

Source(s): IEEE Transactions on Vehicular Technology. Feb2015, Vol. 64 Issue 2, p466-480. 15p.

Abstract: We propose frequency-asynchronous distributed Alamouti-coded orthogonal frequency-division multiplexing (FADAC-OFDM). The proposed scheme effectively mitigates the intercarrier interference (ICI) due to frequency offset (FO) between two distributed ant...

Low-Complexity ICI Suppression Methods Utilizing Cyclic Prefix for OFDM Systems in High-Mobility Fading Channels.

Publication Type: Academic Journal

Source(s): IEEE Transactions on Vehicular Technology. Feb2014, Vol. 63 Issue 2, p718-730. 13p.

Abstract: This paper focuses on a simple intercarrier interference (ICI) suppression scheme that linearly combines the intersymbol interference (ISI)-free part of a cyclic prefix (CP) and its corresponding part in an orthogonal frequency-division multiplexing (O...

Optimal Correlative Coding for Discrete-Time OFDM Systems.

Publication Type: Academic Journal

Source(s): IEEE Transactions on Vehicular Technology. Feb2014, Vol. 63 Issue 2, p987-993. 7p.

Abstract: Frequency-domain correlative coding (CC) has been widely considered to be effective in intercarrier interference (ICI) mitigation in orthogonal frequency-division multiplexing (OFDM) systems due to its potential in the considerable enhancement of the c...

Complementary Coded CDMA Systems With CP-Free OFDM.

Publication Type: Academic Journal

Source(s): IEEE Transactions on Vehicular Technology. Oct2020, Vol. 69 Issue 10, p11515-11528. 14p.

Abstract: In a frequency division complementary coded CDMA (FD-CC-CDMA) system, multiple tuners have to be used for multi-carrier modulation, which has a very high complexity and power consumption. In this paper, we propose a CP-free OFDM scheme to implement mul...
