On the Performance of Cooperative Relaying Systems with NOMA in κ−μ Fading Environment.

Publication Type: Academic Journal

Source(s): Wireless Communications & Mobile Computing. 4/23/2022, p1-15. 15p.

Abstract: Nonorthogonal multiple access (NOMA) is considered to be a promising solution for the fifth generation (5G) wireless networks. The performance of the 5G wireless networks in terms of outage probability, achievable rate, and other important network perf...

Design of optimized distributed Goppa codes and joint decoding at the destination.

Publication Type: Academic Journal

Source(s): Telecommunication Systems. Nov2022, Vol. 81 Issue 3, p341-355. 15p.

Abstract: In this paper, we propose a Goppa coded-cooperative (GCC) diversity scheme for a single-relay setting where a source communicates with a destination with the help of a relay in a two-time-slot transmission. Two Goppa codes are distributed over the sour...

Age-of-Information in First-Come-First-Served Wireless Communications: Upper Bound and Performance Optimization.

Publication Type: Academic Journal

Source(s): IEEE Transactions on Vehicular Technology. Sep2022, Vol. 71 Issue 9, p9501-9515. 15p.

Abstract: This article establishes an analytical framework for the upper bound on the average Age-of-Information (AoI) in first-come-first-served (FCFS) wireless communications where a certain level of outage probability is unavoidable. To begin with, we analyze...

A New Reconfigurable Intelligent-Surface-Assisted LoRa System.

Publication Type: Academic Journal

Source(s): IEEE Transactions on Vehicular Technology. Aug2022, Vol. 71 Issue 8, p9055-9060. 6p.

Abstract: Although LoRa modulation can achieve low-power and long-range transmission, its performance is significantly affected by fading channels. On the other hand, its low data rate limits the capacity. To mitigate these disadvantages, a new reconfigurable in...

Fading-ratio-based selection for massive MIMO systems under line-of-sight propagation.

Publication Type: Academic Journal

Source(s): Wireless Networks (10220038). Nov2022, Vol. 28 Issue 8, p3525-3535. 11p.

Abstract: Massive multiple-input multiple-output (MIMO) enables increased throughput by using spatial multiplexing. However, the throughput may severely degrade when the number of users served by a single base station increases, especially under line-of-sight (L...

Two Interval Upper-Bound Q -Function Approximations with Applications.

Publication Type: Academic Journal

Source(s): Mathematics (2227-7390). Oct2022, Vol. 10 Issue 19, p3590. 15p.

Abstract: The Gaussian Q-function has considerable applications in numerous areas of science and engineering. However, the fact that a closed-form expression for this function does not exist encourages finding approximations or bounds of the Q-function. In this ...
