Abstract

Orthogonal Frequency-Division Multiplexing (OFDM) has become the preferred modulation scheme for both broadband and high bitrate digital wireless protocols because of its spectral efficiency and robustness against multipath interference. Although the components and overall structure of different OFDM protocols are functionally similar, the characteristics of the environment for which a wireless protocol is designed often result in different instantiations of various components. In this paper we present a new baseband processing transmitter case, namely 802.15.3 (WUSB), to existing OFDM framework which consists highly parametrized code in Bluespec for two different wireless baseband processing cases, namely 802.11a (WiFi) and 802.16 (WiMAX). The design cycle for transmitter of WUSB took only six week's for two designers which were not familiar with Bluespec, WUSB protocol or the OFDM framework.
