—One of themajor challenges in supportingmultimedia services over Internet protocol (IP)-based code-division mul- tiple-access (CDMA) wireless networks is the quality-of-service (QoS) provisioning with effi cient resource utilization. Compared with the circuit-switched voice service in the second-generation CDMA systems (i.e., IS-95), heterogeneous multimedia applica- tions in future IP-based CDMA networks require more complex QoS provisioning and more sophisticated management of the scarce radio resources. This paper provides an overview of the CDMA-related QoS provisioning techniques in the avenues of packet scheduling, power allocation, and network coordination, summarizes state-of-the-art research results, and identifi es further research issues.

排课问题是一个有约束的、多目标的组合优化问题,并且已经被证明是一个NP完全问题。 遗传算法借鉴生物界自然选择和自然遗传机制,使用群体搜索技术,尤其是用于处理传统搜索方法难以解决的复杂的和非线性的问题。经过近40年的发展,遗传算法在理论研究和实际应用中取得了巨大的成功,本文将遗传算法用于排课问题的求解,首先讨论了排课问题中的影响因素、主要约束条件、求解目标和难点,并用数学模型完整地描述了排课问题。其次对多个模糊排课目标进行了定量分析,建立了排课优化目标空间。针对排课问题研究了染色体编码方式以及遗传算子的设计,提出了适应度函数的计算方法。最后对排课问题进行了实验。实验结果表明,其过程的目标值跟踪显示,算法稳健趋优,所得结果令人满意。-Course Scheduling problem is a constrained, multi-objective optimization problem, and has proven to be a NP complete problem. Genetic algorithms reference biosphere and the natural genetic mechanism of natural selection, using the group search technology, particularly the traditional search methods for handling complex and difficult to solve nonlinear problems. After nearly 40 years of development, the genetic algorithm in the theoretical study and practical application was a great success, this paper genetic algorithm for solving the course timetabling problem, first discussed the impact of factors in the course arrangement, the main constraints, to solve goals and difficulties, and a complete mathematical model to describe the course arrangement.

— Performance comparison of multiuser OFDM-TDMA and OFDMA systems by considering physical and link cross-layer behavior is conducted in this work. We provide a new framework for performance evaluation that centers on “ scheduling” with several different subcarrier/bit allocation schemes. The performance metrics include: the bit rate, the bit error rate (BER), packet throughput and delay. The instantaneous channel conditions of users are assumed to be available at the base station, which can be achieved by channel estimation at the mobile terminal (MT), and then fed back to the base station through a control channel. To perform the link layer comparison, we model the Rayleigh fading channel with a nite-state Markov chain, and adopt the M/G/1 queueing model as the analytical tool. Computer simulation is performed to verify conducted analytical results-— Performance comparison of multiuser OFDM-TDMA and OFDMA systems by considering physical and link cross-layer behavior is conducted in this work.
