摘要

正交频分复用（OFDM）系统存在一些缺点，如对同步的严格要求和频谱效率较低。基于正交幅度调制的滤波器组多载波（FBMC）系统（QAM-FBMC）被认为是 OFDM 方案的有效替代方案，因此受到越来越多的关注。本文获得了采用单抽头均衡的 QAM-FBMC 系统的误码率 (BER)。此外，还推导出误码率的渐近表达式（对于大量子载波）和误码率的近似表达式。数值结果表明，推导出的误码率表达相当准确。

On the performance of QAM-FBMC systems in frequency-selective channels

Orthogonal frequency division multiplexing (OFDM) systems present some shortcomings such as strict requirements for synchronization and reduced spectral efficiency. Filter bank multicarrier (FBMC) systems based on quadrature amplitude modulation (QAM-FBMC) have attracted increasing attention since they are considered an effective alternative to OFDM schemes. In this paper, the bit error rate (BER) of QAM-FBMC systems with single-tap equalization, is obtained. Moreover, the asymptotic (for a large number of subcarriers) expression of the BER and an approximate expression of the asymptotic BER are derived. The numerical results show that the derived BER expressions are quite accurate.
