In broadband OFDM wireless communications, data symbol detection commonly requires a pilot-aided frequency channel estimation. A partial estimate is first computed from known symbols (pilots), frequencially multiplexed into the data. Estimation over the full bandwidth is then performed by frequency interpolation. In a multipath context, a strong fading effect may seriously degrade the channel estimation...
In this paper, a fully integrated Doherty power amplifier (DPA) for application in IEEE 802.11a wireless local area network (WLAN) transmitters is proposed. The DPA exhibits an output power at its 1 dB compression point of 22 dBm with a corresponding power added efficieny (PAE) of 25 %. Within a 6dB-backoff the PAE is still 20 %, which among the highest reported for Doherty amplifiers fully integrated...
