Filter bank multicarrier (FBMC) techniques are emerging alternatives to the widely used orthogonal frequency division multiplexing (OFDM) schemes for applications such as machine type communications or cognitive radio. Recently an FBMC scheme based on a sine prototype filter with overlapping factor $K=2$ termed FBMC-PAM has been introduced. It assures an interesting performance, a reduced system latency and is robust to carrier-frequency offset. After presentation of the system model, an analytical expression of the BER of the single-tap sub-channel equalizer for the considered FBMC-PAM system operating in frequency-selective Rayleigh fading channel is obtained and compared with simulation results. Moreover, a performance comparison with an approximate single-tap sub-channel equalizer and with the previously proposed FBMC-PAM-2M, is presented.

滤波器组多载波（FBMC）技术是对诸如机器类型通信或认知无线电之类的应用广泛使用的正交频分复用（OFDM）方案的新兴替代方案。最近，基于具有重叠因子的正弦原型滤波器的FBMC方案$ķ=2$引入了FBMC-PAM。它确保了有趣的性能，减少了系统延迟，并且对载波频率偏移具有鲁棒性。在介绍了系统模型之后，获得了在频率选择瑞利衰落信道中工作的所考虑的FBMC-PAM系统的单抽头子信道均衡器BER的解析表达式，并将其与仿真结果进行了比较。此外，提出了与近似单抽头子信道均衡器和先前提出的FBMC-PAM-2M的性能比较。
