Adaptive Resource Allocation Scheme of Multi-service Subcarrier Adjusting and Borrowing for OFDM-Based Systems

摘要

摘要: 該文研究了衰落信道條件下的無(wú)線資源分配問(wèn)題。提出了一種適用于多用戶OFDM系統(tǒng)中的多業(yè)務(wù)間子載波借調(diào)的自適應(yīng)資源分配機(jī)制。該機(jī)制能夠聯(lián)合考慮信道衰落情況和業(yè)務(wù)的服務(wù)質(zhì)量要求，在不同的業(yè)務(wù)間調(diào)整和借用子載波分配來(lái)最大化系統(tǒng)的容量和性能。仿真結(jié)果表明，該文提出的分配機(jī)制能改善OFDM系統(tǒng)的性能。

Abstract: In this paper, an adaptive resource allocation scheme of multi-service subcarrier adjusting and borrowing for multi-user OFDM-based systems is proposed. According to channel fading condition and quality of service of users, the scheme is used to maximize the system capacity and performance by adjusting and borrowing subcarrier among multi-service. The simulation results illustrate that the scheme proposed in this paper can improve performance OFDM-based systems.
