OFDM for Optical Communications (2009, background): “In the existing OFDM literature these impairments are usually classified in terms of their source, for example, frequency offset between transmitter and receiver local oscillator [65], Doppler spread in the channel [66], and a variety of phase noise models with characteristics that depend on the mec”
Performance degradation of OFDM systems due to Doppler spreading (2006, methodology): “Doppler frequency in Hz C /I (d B ) from Equation (25) Reference [9] Lower bound from Reference [8] Reference [5],[6]”
Great expectations: the value of spatial diversity in wireless networks (2004, methodology): “In SISO OFDM, previous studies have quantified the effects of ICI on the system performance [220, 216, 167, 169, 150].”
Channel Estimation for OFDM (2014, background): “As a result, the channel can be assumed as constant over one OFDM symbol, and thus ICI can be omitted for practical OFDM systems [29].”
Bounding performance and suppressing intercarrier interference in wireless mobile OFDM (2003, methodology): “If all eigenvalues , are distinct, the BER for binary phase-shift keying (BPSK) and quaternary phase-shift keying (QPSK) can be found as [15] (11) where , for BPSK, and for QPSK.”
Low-complexity equalization of OFDM in doubly selective channels (2004, background): “In time- and frequency-selective—or doubly selective— fading, however, the orthogonality of OFDM is lost, leading to subcarrier interference that greatly complicates optimal data detection [3]–[8].”
OFDM and Its Wireless Applications: A Survey (2009, background): “It can be proved in [4] and [76] that the power of ICI is upper bounded by”
Intercarrier interference in MIMO OFDM (2002, background): “In [8], the focus is on the wide-sense stationary uncorrelated scattering (WSSUS) [9] channel to show that if the OFDM block duration is greater than 8% of the channel coherence time, then the SINR (due to ICI) is less than 20 dB (see also [10] and references therein).”
Time-variant channel estimation using discrete prolate spheroidal sequences (2005, background): “Doppler bandwidth, stays below a certain threshold, the intercarrier interference can be neglected for the receiver side processing [25].”
