CD_Telephoning
Relaying and orthogonal frequency division multiple
access (OFDMA) are the accepted technologies for emerging
wireless communications standards. The activities in many
wireless standardization bodies and forums, for example IEEE
802.16 j/m and LTE-Advanced, attest to this fact. The availability
or lack thereof of efficient radio resource management (RRM)
could make or mar the opportunities in these networks. This
paper therefore provides a comprehensive RRM algorithm for
OFDMA-based multi-cellular fixed relay networks in a way to
ensure fairness among users with minimal impact on the network
throughput (in contrast, pure opportunistic RRM techniques
always favor users with good channel conditions

Reconfigurable-flight-control
精密控制结构需要满足先进飞机的使命和对其引航的要求。这就要求飞行器的性能必须满足在低空飞行,低速飞行和大迎角攻击性飞行,全天候,昼夜工作的条件,并且新的控制技术应该成熟。这项工作提出了飞行控制时,状态变量和控制输入是由预先确定的限制范围内的系统控制系统的设计理念。在设计过程使用动态规划的概念。其基本思想涉及非二次泛函最小化。由于一系列限制因素,建议使用光滑函数。同时提出了该综合方法的优点。我们利用对F-18战斗机的纵向控制配置来说明该设计方法。(Indirect adaptive control for reconfigurable flight control is advocated. Specifically,
online static system identification using a moving window/batch estimation is implemented.
The ensuing linear regression is augmented with an intercept. The intercept parameter is
included to address the effects of trim change associated with the occurrence of a control surface
failure. Parameter estimate information is used to adjust the inner loop’s control gains, and
a command derived from the intercept estimate is fed forward to automatically retrim the aircraft.
The tracking performance of this automatic retrimming method, which relies on system
identification, surpasses the conventional approach of exclusively relying on integral action
for retrimming. These adaptive and reconfigurable flight control concepts are illustrated in
the context of a fighter aircraft’s pitch plane dynamics. The novel adaptive and reconfigurable
flight control system successfully handles a 50 per cent horiz)

Multi-User-Diversity-vs
In a multiple transmit antenna, single antenna per receiver downlink channel with limited channel state feedback, we consider the following question: given a constraint on the total system-wide feedback load, is it referable to get low-rate/coarse channel feedback from a large number of receivers or high-rate/high-quality feedback from a smaller number of receivers? Acquiring feedback from many receivers allows multi-user diversity to be exploited, while high-rate feedback allows
for very precise selection of beamforming directions. We show that there is a strong preference for obtaining high-quality feedback, and that obtaining near-perfect channel information from as many receivers as possible provides a significantly larger sum rate than collecting a few feedback bits from a large number of users.
