A common phenomenon of aggregate audience behavior in which the audience for one program tends to be disproportionately represented in the audience for other programs on the same channel. 累计受众行为的一种表现。一个节目的受众不合比例地成为同一频道另一节目的受众。
Considering the aggregate spectral density of all the channel impairments, the channel attenuation and the constraint of power spectral density to the maximum bit rates of subchannels, a bit loading and power allocation algorithm is proposed for DMT-based multicarrier communication system. 在噪声干扰,信道衰减和一定频段上功率谱密度对子信道最大传输位数限制的条件下,得到了一种实用的离散多音频多载波通信系统的功率分配和数据位加载算法。
Chapter 2 is detailed to introduce the realization principle of the adaptive multilevel modulation and its deciding threshold of choosing modulated method aggregate under the single channel, and discussed some main parameters that have great impact to modulation performance. 论文第二章详细介绍了单个信道条件下自适应多元调制方式的实现原理及其选择调制方式集判决门限的确定,同时对调制性能影响较大的几个重要参数进行了分析。
The credit policy and the interest rate policy play their roles not only by changing money aggregate, but also through policy expectation channel. They influence asset prices and the CPI in a more direct way than money aggregate. 信贷额变化和基准利率变化不仅通过货币量变化发生作用,更通过政策预期渠道作用于资产价格和CPI,影响方式更加直接。
In the process of western development, the lack of aggregate investment, inadequate investment origin channel, irrational investment structure, and poor investment efficiency have been the key restrictions for economy development. 在西部地区经济发展的过程中,投资总量不足、投资来源渠道不够畅通、投资结构不合理、投资效率低下等问题已成为制约西部地区经济发展的重大因素。
First, for the purpose of improving the saturation throughput of 802.11n system in non-ideal channel, the thesis proposed a algorithms which can adjust the length and number of aggregate frame dynamically according to the bit error rate of wireless channel. 综合分析所得结果,以提高在非理想信道下,802.11系统的饱和吞吐量为目的,本文提出了一种依据无线信道误比特率不同,动态调节聚合帧长的思想。
Compared with similar algorithms, the proposed algorithm has some advantage on aggregate throughput performance and improves the fairness of channel allocation of secondary users as well. 与同类算法相比,该算法在总吞吐量性能上具有优势,同时也改善了次级用户之间信道资源分配的公平性。
Meanwhile, considering the high processing capacity and the traffic aggregate character of the mesh gateway, a rate-adaptive gateway congestion control scheme is proposed, aiming at improving the spatial channel reuse and avoiding congestion for single-channel mesh networks. 同时结合Mesh网关的高处理能力和流量汇聚特点,提出一种自适应速率的网关拥塞控制算法,用于提高单信道网络的空间复用性,避免网络拥塞。
