Flexible OFDM transceiver for a high-speed wireless LAN

Orthogonal frequency division multiplexing (OFDM) shows clear benefits as a modulation technique for wireless local area networks (WLAN), and is hence being validated in recent standardization efforts. This paper presents some results of a high-speed OFDM transceiver ASIC recently developed at IMEC. This transceiver provides a large degree of flexibility through programmable parameters with respect to both channel and user requirements. The integration of a high-speed OFDM baseband transceiver on a single ASIC is an important step towards high-capacity WLAN at competitive prices.
