FBMC系统的闭型误码率
Closed-Form Bit Error Probabilities for FBMC Systems
摘要：
本文分析了在加性高斯白噪声（AWGN）和频率平坦瑞利信道下，考虑每个子载波的频率平坦性，在滤波器组多载波（FBMC）系统中部署非理想原型滤波器所产生的数据重构效果。通过研究原型滤波器的误比特率（BER）效应，逐步增加场景复杂度来实现这一目标。尽管复杂，精确和近似的比特错误概率（BEP）表达式描绘的BER退化分析任何FBMC原型滤波器。数值结果表明，所提出的BEP表达式与FBMC系统的模拟BER性能完全匹配，无论原型滤波器的选择。
英文摘要：
This paper analyses the data reconstruction effects emerged from the deployment of non-perfect prototype filters in Filter Bank MultiCarrier (FBMC) systems operating over Additive White Gaussian Noise (AWGN) and frequency-flat Rayleigh channels considering frequency-flatness for each subcarrier. This goal is attained by studying the Bit Error Rate (BER) effects of the prototype filters, increasing the scenario complexity progressively. Despite the complexity, both exact and approximate Bit Error Probability (BEP) expressions portray the BER degradation analytically for any FBMC prototype filter. Numerical results demonstrate that the proposed BEP expressions match perfectly with the simulated BER performance for FBMC systems, regardless of the prototype filter choice.
