Computer Network | TDMA and FDMA: In this tutorial, we will learn about two channelization processes for multiple accesses, namely TDMA, FDMA.
random access in frequency hopped airborne networks However, a static schedule, also known as Time Division Multiple Access or TDMA, is shown to have very large delays for high traffic loads. Dynamic scheduling can achieve the throughput of TDMA and the delay of random access, but ... D ...

FDMA is the easiest multiplex access mode in satellite communication,and it has wide application. In this paper,we have studied the principle of FDMA technology and its application. We also have analyzed the relationship between satellite's power and bandwidth, power control technology, guard band ...
It is shown that GFDMA offers advantages over SC-FDMA with respect to power/spectral efficiency. Such power/spectral efficiency can provide considerable performance improvements in future wireless communication networks. 展开 被引量: 39 年份: 2010 ...
in LTE networks that are applicable to D2D communications [23]. The performance of LTE power control scheme and a utility function-based distributed power control scheme are compared, where dynamic resource allocation and mode selection are implemented. In [24], Yu et al. have analyzed different...

Computer simulations are used to evaluate system performance in terms of dropped packet ratio and average channel setup delay. Only the bursty voice traffic is considered for real-time transmission. Priority-based two-stage algorithms are found to provide good performance, where the first stage is ...
This paper addresses the problem of allocating spatially reused frequency channels in ad hoc networks to satisfy data rate constraints on various links. The data rate requirement of each link is satisfied by using adaptive modulation. Power control is used to maintain the required signal to interfere...
