Compact Ultramassive Antenna Array (CUMA) is a pioneering paradigm that leverages the flexibility of the Fluid Antenna System (FAS) to enable a simple multiple access scheme for massive connectivity without the need for precoding, power control at th

This letter provides exact expressions for the sum statistics of independent and identically distributed Ricean random variables. More precisely, we derive new compact, fast, and manageable solutions for both the probability density function and the

Opportunistic systems take advantage of the wireless communication channel random behavior, since transmission is made only when fading amplitude is above a threshold value, which is calculated based on a transmission probability. This type of transm

The authors derive a closed-form exact expression and a fast convergent series for the probability of phased-array detection of non-fluctuating targets embedded in complex white Gaussian noise. To be realistic, they assume that the amplitude of the t

The performance of encoded opportunistic transmission schemes in wireless channels affected by Rayleigh fading and additive white Gaussian noise (AWGN) is analyzed. In opportunistic transmission, the information is transmitted only when the fading am

The importance of quality virtual education has been shown recently. However, there are certain areas of knowledge for which it is difficult to replace face-to-face education with virtual education, mainly, when laboratories are required or equipment

Non-orthogonal multiple access (NOMA) techniques have been proposed for fifth generation (5G) mobile systems, among them stands out sparse code multiple access (SCMA), which is a code domain NOMA (C-NOMA) technique. With SCMA, the system can be overl

In this paper we propose an opportunistic transmission in which the fading characteristics and interference are considered. The opportunism is considered in the sense that transmissions are made just when the fading amplitude is above a threshold val

In this paper, an approach to evaluate the cellular spectral efficiency of the uplink of MC-CDMA systems employing fractional frequency reuse (FFR) and soft frequency reuse (SFR) is proposed. For this, an algorithm to calculate the cell coverage radi
