摘要

在本文中，我们开发了一种基于MC-CDMA的蜂窝认知无线网络，该网络能够在共享频段内与许多传统的局域网共存。认知MC-CDMA发射机利用易于获取的射频环境知识，即每个遗留系统的带宽和频率位置，通过自适应传输减轻相应接收机的干扰。我们将开发一种计算自适应传输参数的算法，并对该方法的误差性能进行解析和数值分析。

Spectrum sharing with legacy RANs using cognitive MC-CDMA

In this paper we develop a cellular cognitive radio network based on MC-CDMA, which is able to coexist with a number of legacy RANs in a shared band. Using the simple-to-obtain knowledge of RF environment, namely the bandwidth and frequency location of each legacy system, the cognitive MC-CDMA transmitter mitigates the interference in the corresponding receivers by adaptive transmission. We will develop an algorithm for calculating the adaptive transmission parameters and elaborate on error performance of this approach analytically and numerically.
