Cyclic prefixing or zero padding for wireless multicarrier transmissions?
TLDR
Zero padding (ZP) of multicarrier transmissions has been proposed as an appealing alternative to the traditional cyclic prefix (CP) orthogonal frequency-division multiplexing (OFDM) to ensure symbol recovery regardless of the channel zero locations. Expand

Complex-field coding for OFDM over fading wireless channels
TLDR
We quantify the maximum achievable diversity order for independent and identically distributed (i.i.d.) Rayleigh-fading channels, and provide design rules for achieving the maximum diversity order. Expand

OFDM or single-carrier block transmissions?
TLDR
We compare two block transmission systems over frequency-selective fading channels: orthogonal frequency-division multiplexing (OFDM) versus single-carrier modulated blocks with zero padding (ZP). Expand

Direct observation of calcium-independent intercellular ATP signaling in astrocytes.
Adenosine triphosphate (ATP) is assumed to be involved in the regulation of many extracellular signaling systems including calcium wave propagation. So far all supportive evidence is indirect, suchExpand

Outage mutual information of space-time MIMO channels
TLDR
We derive analytical expressions for the probability density function (pdf) of the random mutual information between transmitted and received vector signals of a random space-time independent and identically distributed multiple-input multiple-output (MIMO) channel, assuming that the transmitted signals from the multiple antennas are Gaussian i.i.d..

Error performance of transmit beamforming with delayed and limited feedback
TLDR
We study the effect of delayed and limited-rate codebook index feedback on the error rate performance of TB systems over Rayleigh fading channels, and provide analytical error rate expressions. Expand
