Sparse Equalizers for OFDM Signals with Insufficient Cyclic Prefix
(
Institute of Electrical and Electronics Engineers Inc.
, 2018 , Article)
The cyclic prefix (CP) is appended in orthogonal frequency division multiplexing (OFDM) signals to combat inter-symbol interference (ISI) and inter-carrier interference (ICI) induced by the communication channel, which ...
Maximum likelihood detection of precoded SFBC in frequency-selective fading channels
(
Institute of Electrical and Electronics Engineers Inc.
, 2018 , Conference Paper)
In this paper, we derive the maximum likeli-hood detector (MLD) for precoded space-frequency block coded (SFBC) systems where orthogonal frequency divi-sion multiplexing (OFDM) is incorporated. The obtained results reveal ...
Reduced-complexity sparsity-aware joint phase noise mitigation and channel equalization in OFDM receivers
(
Elsevier B.V.
, 2018 , Article)
A major performance and complexity limitation in direct-conversion broadband wireless transceivers is the phase noise (PN) resulting from the inevitable imperfections in the fabrication process of the crystal oscillator. ...
