Abstract

This paper introduces a study and an implementation of filters in the digital part of an Orthogonal Frequency Division Multiplexing (OFDM) based transmitter. An efficient computational technique is presented for design with interpolation filters and discusses the corresponding VLSI architecture issues. By exploiting the redundancy into the cyclic prefix part of the OFDM symbol, the computational load of the transmitter is reduced by approximately 20% for the IEEE 802.11 WLAN standard.

Keywords: OFDM WLAN digital ¯lters VLSI architecture
