    • A method for optimizing radio resource assignment by using a genetic algorithm to which a goal programming scheme is applied, and a computer readable medium recording a program which uses the same are provided to obtain an optimal solution easily, to enhance a solution convergence speed, to reduce unnecessary power consumption by lowering system complexity, and to optimize resources and system variables. A method for optimizing radio resource assignment comprises the following several steps. Degree of satisfaction to the goal is determined, and the first front is assigned to entities which satisfy the first degree of satisfaction to the goal which is set up according to the request of resources or a system(SG1). Dummy fitness is assigned to entities to which the first front is assigned(SG2). Fitness is shared like a conventional NSGA(Non-dominated Sorting Genetic Algorithm), and the front is increased(SG3,SG4). If the steps are repeated, other degree of satisfaction to the goal for each front can be set up. If the fronts are assigned to all the entity group(S1), reproduction(S2), cross(S3) and mutation(S4) are passed, and then a generation number is increased, and the steps S1-S4 are repeated until the generation number arrives at a maximum generation number.

    • A platform and a method for reconfiguring a reconfigurable base station are provided to offer a user high quality service as well as to enhance efficiency of frequency resources by changing frequencies or services selectively according to an environment, a user request or QoS(Quality of Service). A platform for reconfiguring a reconfigurable base station includes a CR(Cognitive Radio) function unit(100) and an SDR(Software Defined Radio) platform(200). The CR function unit actively recognizes a situation like a channel feature caused by different frequencies, time assignment distribution or unique environment characteristics and assigns available wireless resources to a user based on the recognized information. The SDR platform reconfigures flexibly a transmitting or receiving system like a base station or a terminal via a software based on transmitting or receiving algorithm information like information on frequencies, bandwidth, a multiplexing scheme, a modulating/demodulating scheme, channel coding, transmission power and others.
    • 提供了一种用于重新配置可重新配置的基站的平台和方法,以通过根据环境,用户请求或QoS(服务质量)选择性地改变频率或服务来提供用户高质量服务以及提高频率资源的效率, 。 用于重新配置可重构基站的平台包括CR(认知无线电)功能单元(100)和SDR(软件定义无线电)平台(200)。 CR功能单元主动地识别由不同频率,时间分配分配或独特环境特征引起的频道特征的状况,并且基于所识别的信息向用户分配可用的无线资源。 SDR平台通过基于诸如频率,带宽,复用方案,调制/解调方案,信道编码,传输功率等信息的发送或接收算法信息,通过软件灵活地重新配置诸如基站或终端的发送或接收系统。 其他。
