Upper and lower bounds on the BER performance of the maximum likelihood detection of uncoded transmission in a SC-FDMA setting are derived for a Rayleigh fading channel. Approximated closed-form expressions are derived for the lower bound of the BER performance for high and low SNR regimes. These derivations are validated by simulation.

simultaneous routing and resource allocation has been considered in wireless networks for its performance improvement. in this paper we propose a cross-layer optimization framework for worst-case queue length minimization in some type of fdma based wireless networks, in which the the data routing and the power allocation problem are jointly optimized with fuzzy distributed h∞ control strategy ....

This paper investigates the information freshness of Industrial Internet Things (IIoT) systems, where each IoT device makes a partial observation common target and transmits update to central receiver recover complete observation. We consider age collection (AoC) performance as measure freshness. Unlike conventional (AoI) metric, instantaneous AoC decreases only when all cooperative packets for...

Bandwidth, power and collision are considered as three important resources in wireless networks. Therefore, how to manage these resources becomes a effect on wireless ad hoc network. These effects are not present in wire line networks, and evaluation of available bandwidth in wireless networks a difficult task. Furthermore, in wireless medium the available resources also vary with the protocol ...

This paper reviews recent work on spread spectrum network capacity. The network is shown to have a capacity that is equitably shared amongst the users via power control. This solution is much simpler than the bandwidth partitioning of the FDMA/reuse approach. The capacity gains from using spread spectrum, arising from the averaging and multiplexing, are also emphasised.
