A single chip DMT modem for high-speed WLANS

This paper presents the architecture and implementation of a single chip 25 Mbps discrete multi-tone (DMT) modem. It forms the baseband processor for a 25 Mbps wireless local area network operating in the newly created 5 GHz U-NII band. The 243000 transistor chip is implemented in 0.6 /spl mu/m TLM...

Description
Summary:This paper presents the architecture and implementation of a single chip 25 Mbps discrete multi-tone (DMT) modem. It forms the baseband processor for a 25 Mbps wireless local area network operating in the newly created 5 GHz U-NII band. The 243000 transistor chip is implemented in 0.6 /spl mu/m TLM CMOS, occupies 5.1 mm by 5.6 mm, and is designed to run at 50 MHz with a 2.5 V supply.
