A Practical Low Cost Architecture for a MB-OFDM Equalizer (ECMA-368)
Robert Simon Sherratt, Oswaldo Cadenas, Runfeng Yang · 2007
The relative fast processing speed requirements in wireless personal area network (WPAN) consumer based products are often in conflict with their low power and cost requirements. In order to solve this conflict the efficiency and cost effectiveness of these products and the underlying functional modules become paramount. This paper presents a low-cost, simple, yet high performance solution for the receiver channel estimator and equalizer for the mutiband OFDM (MB-OFDM) system, particularly directed to the WiMedia Consortium Physical Later (ECMA-368) consumer implementation for wireless-USB and fast Bluetooth. In this paper, the receiver fixed point performance is measured and the results indicate excellent performance compared to the current literature.
