Abstract

The paper presents a study on the realization of equalizer IP (intellectual property) blocks for FPGA-based realization of multicarrier modem cores applying filter bank based principle and OQAM modulation. New equalization IP blocks with appropriate architectures for two different modem applications are proposed - following the ADSL standard and according to the 802.11 wireless communication standard (WiFi). We estimated the impact of equalization IPs on the frequency, the area efficiency and the SNR of the FPGA-based modem realizations.
