Low-complexity design of PHY/MAC modem processor for WiMedia UWB systems

Abstract

We propose a low-complexity design and implementation for baseband modem processors in WiMedia UWB systems. The proposed processor is a MAC-PHY integrated baseband processor that complies with Standard 1.1 (ECMA368/369) and supports full mode up to 480 Mbps. It realizes low power and low area by adopting 4-parallel structures to decrease operating frequency. It was implemented with a CMOS 0.13 μm process, has an operating frequency of 152 MHz, and was synthesized with approx. 1.6M gates.
