Abstract
This paper has evaluated the overhead requirements for IOTA pulse shaping filters employed in faster-than-Nyquist multicarrier systems. Faster-than-Nyquist signaling has shown the promise of improving bandwidth efficiency, but comes at the cost of increased processing complexity in the transceiver. The IOTA filter being one of the blocks contributing for the processing overhead, different architectural options have been evaluated. A comparison is drawn between the architectures of the IOTA filter and the suitable architecture with moderate hardware overhead is chosen for implementation.
