Abstract

The FBMC-OQAM waveform recently has received a lot of interest due to its outstanding spectral characteristics. However, that comes with the cost of a new built-in interference introduced between its subcarriers which triggered the need for new transceiver techniques. In this letter, we propose an efficient equalization technique that utilizes the Wiener filter. Unlike the state-of-the-art studies, we consider the channel estimation errors within the design of the Wiener filter. This will permit improving the performance accuracy of the FBMC-OQAM system in very high-speed scenarios. We propose a straightforward analytical development for our study and conduct a numerical analysis via Monte Carlo simulations where we compare the performance of the proposed technique with other recent studies.
