Description: 本文提
出了基于功率预留的准入控制策略。首先介绍一种资源分配算法，该算法将可用信
道完全分配从而实现基站发射功率最小化。在此基础上，分别为小区间切换用户和
小区内切换用户设计预留策略，并根据系统的业务载荷自适应地调整功率预留量，
从而实现GOS的最优化。
-there exists a fundamental tradeoff between bandwidth and power. In this thesis, we
propose a novel admission control scheme based on power reservation. Foremost, we
introduce a joint subchannel and power allocation algorithm for WiMAX system, which
minimizes the overall downlink transmit power by utilizing all available subchannels.
Based on this, we propose two power reservation schemes for inter-cell handoff calls and
intra-cell handoff calls, respectively. The amount of reserved power is determined in an
adaptive manner for optimizing the metric of Grade of Service(GoS).

Description: In this paper, a multicell OFDMA WiMAX network is considered for uating the performance analysis both in uplink and downlink .The QOS parameters like blocking time, download time and BER of the network are discussed on various physical layer conditions like modulation techniques, channel models and different MIMO structures. The Erlang capacity of the system is formulated and based on this the optimum admission control and modulation technique is chosen. -In this paper, a multicell OFDMA WiMAX network is considered for uating the performance analysis both in uplink and downlink .The QOS parameters like blocking time, download time and BER of the network are discussed on various physical layer conditions like modulation techniques, channel models and different MIMO structures.
