A wireless LAN demodulator in a Pamette: design and experience

We have implemented the digital section of a wireless local area network (WLAN) demodulator in a reconfigurable interface card called the PCI Pamette. The entire baseband section of the demodulator has been implemented in the Pamette and a simple analog to digital mezzanine board. This is the second implementation of the demodulator, the first being a card-based design using a mixture of discrete and reconfigurable logic. The Pamette implementation took far less time to complete than the card-based design. Moreover, the reconfigurable substrate is much more versatile. This paper describes the Pamette implementation and discusses our experiences with the two different design styles and technologies.
