Filter Bank Multi-Carrier (FBMC) has been identified by many authors as a possible successor for orthogonal frequency-division multiplexing in 5G. In this paper, we consider pilot-symbol aided channel estimation in FBMC. To deal with the imaginary interference, inherently caused in FBMC, we employ auxiliary symbols. In contrast to previous works, we propose to use multiple auxiliary symbols per pilot which decreases the peak-to-power average ratio and, for certain operation points, also increases the achievable capacity. The applicability of our channel estimation method is then validated through real world measurements, where we show that multiple auxiliary symbols lead to a higher throughput for practical relevant signal-to-noise ratios.
