Efficient real-time implementation of a channelizer filter with a weighted overlap-add approach

We investigate a real-time implementation of a channelizer filter for joint digital down-conversion, matched-filtering and sample-rate conversion of multicarrier signals in coherent access networks. A complexity reduced design is proposed and synthesized with low performance penalty in a system experiment.
