The state-of-the-art eigenvalue-based spectrum sensing methods only consider the partial
information of eigenvalues, such as the maximum, minimum, and mean values to make …

In this letter, a highly accurate approximate approach for the sum of arbitrary correlated
Weibull random variables is proposed. Specifically, closed-form approximate expressions …

We propose a unified approach to approximate the probability density function and the
cumulative distribution function of a sum of independent channel envelopes following …

The coherent laser signals of optical wireless communication suffer dramatic intensity
fluctuations due to the atmospheric turbulence effect. A larger receiver aperture could only …

Approximations to sums of random variables (RVs) have been a longstanding issue in view
of the usual intricacy of the exact sum statistics. In this letter, a new technique called …

In this paper, we study the performance of L-branch maximal-ratio combining (MRC)
receivers operating over independent Weibull-fading channels. Our main result is a very …

In this letter, a statistical framework is presented for the sum of-and double-random variates.
The statistical results are applied in two scenarios: i) communication systems with maximum …

This paper has collectively exploited cognitive radio (CR), non‐orthogonal multiple access
(NOMA) and multiple‐input‐multiple‐output (MIMO) communication systems in order to …

The photonics-aided terahertz (THz) signal generation method has the advantages of large
available bandwidth and easy integration with fiber optic networks. However, THz wireless …

We experimentally demonstrate the transmission of 20-Gbaud QPSK millimeter-wave
signals within a 1.2-km wireless range at 128-GHz using constant-modulus-algorithm (CMA) …
