Resource Allocation in Downlink OFDM Wireless Systems with User Rate Allowed Regions
Abstract In this paper, a novel adaptive resource allocation in downlink orthogonal frequency division multiplexing wireless system is investigated. Different from the conventional algorithms, user rate allowed regions are considered. That is, not only the user minimum rate requirements are to be sa...

| 520 | |a Abstract In this paper, a novel adaptive resource allocation in downlink orthogonal frequency division multiplexing wireless system is investigated. Different from the conventional algorithms, user rate allowed regions are considered. That is, not only the user minimum rate requirements are to be satisfied, but also the maximum rate limitations are introduced to make resource allocation more reasonable. Given equal power distribution, a three-round subcarrier assignment is proposed at first to achieve a preliminary performance. Then, waterfilling-based power allocation is designed to guarantee user rate allowed regions and enhance system performance further. Numerical results show that the proposed algorithm ensures users achieving data rates within their allowed regions more precisely. In the mean time, the system throughput and transmit power consumption are reasonably balanced compared to the traditional methods when channel-gain-to-noise-ratio is high. | ||

Different from the conventional algorithms, user rate allowed regions are considered. That is, not only the user minimum rate requirements are to be satisfied, but also the maximum rate limitations are introduced to make resource allocation more reasonable. Given equal power distribution, a three-round subcarrier assignment is proposed at first to achieve a preliminary performance. Then, waterfilling-based power allocation is designed to guarantee user rate allowed regions and enhance system performance further. Numerical results show that the proposed algorithm ensures users achieving data rates within their allowed regions more precisely. In the mean time, the system throughput and transmit power consumption are reasonably balanced compared to the traditional methods when channel-gain-to-noise-ratio is high.

Different from the conventional algorithms, user rate allowed regions are considered. That is, not only the user minimum rate requirements are to be satisfied, but also the maximum rate limitations are introduced to make resource allocation more reasonable. Given equal power distribution, a three-round subcarrier assignment is proposed at first to achieve a preliminary performance. Then, waterfilling-based power allocation is designed to guarantee user rate allowed regions and enhance system performance further. Numerical results show that the proposed algorithm ensures users achieving data rates within their allowed regions more precisely. In the mean time, the system throughput and transmit power consumption are reasonably balanced compared to the traditional methods when channel-gain-to-noise-ratio is high.</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">OFDM</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Resource allocation</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Sum rate</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">User rate allowed region</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Waterfilling</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Ren, Zhanyang</subfield><subfield code="e">verfasserin</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Hu, Bo</subfield><subfield code="e">verfasserin</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Ma, Weiguo</subfield><subfield code="e">verfasserin</subfield><subfield code="4">aut</subfield></datafield><datafield tag="773" ind1="0" ind2="8"><subfield code="i">Enthalten in</subfield><subfield code="t">Wireless personal communications</subfield><subfield code="d">Dordrecht [u.a.] : Springer Science + Business Media B.V, 1994</subfield><subfield code="g">80(2014), 1 vom: 28.

Resource Allocation in Downlink OFDM Wireless Systems with User Rate Allowed Regions |
| abstract |
Abstract In this paper, a novel adaptive resource allocation in downlink orthogonal frequency division multiplexing wireless system is investigated. Different from the conventional algorithms, user rate allowed regions are considered. That is, not only the user minimum rate requirements are to be satisfied, but also the maximum rate limitations are introduced to make resource allocation more reasonable. Given equal power distribution, a three-round subcarrier assignment is proposed at first to achieve a preliminary performance. Then, waterfilling-based power allocation is designed to guarantee user rate allowed regions and enhance system performance further. Numerical results show that the proposed algorithm ensures users achieving data rates within their allowed regions more precisely. In the mean time, the system throughput and transmit power consumption are reasonably balanced compared to the traditional methods when channel-gain-to-noise-ratio is high. |
