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...
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...

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...
