Spectral efficiency in the wideband regime
IEEE Transactions on Information Theory, 2002Summary: The tradeoff of spectral efficiency (b/s/Hz) versus energy-per-information bit is the key measure of channel capacity in the wideband power-limited regime. This paper finds the fundamental bandwidth-power tradeoff of a general class of channels in the wideband regime characterized by low, but nonzero, spectral efficiency and energy per bit ...

Resource Efficiency: A New Paradigm on Energy Efficiency and Spectral Efficiency Tradeoff [PDF]
IEEE Transactions on Wireless Communications, 2014 Spectral efficiency (SE) and energy efficiency (EE) are the main metrics for designing wireless networks. Rather than focusing on either SE or EE separately, recent works have focused on the relationship between EE and SE and provided good insight into the joint EE-SE tradeoff.

The spectral efficiency of linear precoders
Proceedings 2003 IEEE Information Theory Workshop (Cat. No.03EX674), 2004Recent results on the asymptotic empirical eigenvalue distribution of the sum or product of matrices, based on the free probability theory, have enabled the study of the asymptotic limits of linear precoded OFDM systems with MMSE equalization for ergodic and non-ergodic channels.

Spectrally Efficient Optical Communications
Asia Communications and Photonics Conference 2015, 2015The paper reviews most diffuse techniques used for increasing spectral efficiency in optical communication, considering different network segments. Time-frequency packing will be described, and compared to Nyquist wavelength-division multiplexing and orthogonal frequency-division multiplexing.

Spectral Efficiency of Multicarrier CDMA
IEEE Transactions on Information Theory, 2005We analyze the spectral efficiency (sum-rate per subcarrier) of randomly spread synchronous multicarrier code-division multiple access (MC-CDMA) subject to frequency-selective fading in the asymptotic regime of number of users and bandwidth going to infinity with a constant ratio.

Spectrally efficient noncoherent communication
IEEE Transactions on Information Theory, 2002Summary: This paper considers noncoherent communication over a frequency-nonselective channel in which the time-varying channel gain is unknown a priori, but is approximately constant over a coherence interval. Unless the coherence interval is large, coherent communication, which requires explicit channel estimation and tracking prior to detection ...
