Abstract: An adaptive bias control scheme for an Orthogonal Frequency Division Multiplex (“OFDM”) transmitter. The transmitter chain is comprised of class A amplifiers. The amplifiers in the transmit chain are backed off from P1dB to ensure linear amplification of the signal. Amplifier back off is defined as (Amplifier P1dB) minus (Average Signal Power). Since the efficiency of the amplifier decreases in direct proportion, to the back off, it is desirable to minimize back off while maintaining linearity. The back off is dependent on the peak to average power ratio (“PAPR”) of the OFDM waveform. The PAPR is measured on a symbol by symbol basis and the amplifier P1dB is adjusted in proportion to the PAPR of the symbol, maintaining a P1dB sufficient to provide the required back off dictated by the maximum PAPR of the OFDM waveform, but can be lowered for symbols with PAPR below the maximum. The average operating point of the amplifiers is reduced by the adaptive bias control on a symbol-by-symbol basis.
Abstract translation: 用于正交频分复用（“OFDM”）发射机的自适应偏置控制方案。 发射机链由A类放大器组成。 发射链中的放大器从P1dB退出，以确保信号的线性放大。 放大器退避定义为（放大器P1dB）减（平均信号功率）。 由于放大器的效率以直接比例降低，因此在保持线性的同时，希望最小化退避。 退避取决于OFDM波形的峰值与平均功率比（“PAPR”）。 PAPR是按符号进行测量的，并且放大器P1dB与符号的PAPR成比例地调整，保持足够的P1dB以提供由OFDM波形的最大PAPR所规定的所需的反向，但可以降低 符号PAPR低于最大值。 通过基于逐个符号的自适应偏置控制来减小放大器的平均工作点。

Abstract: A method to adjust either the detection sensitivity threshold (e.g., the clear channel assessment (CCA) for an 802.11 complaint wireless transceiver) and/or the receiver communication sensitivity threshold (e.g., the start of packet (SOP) for an 802.11 complaint wireless transceiver) to improve performance in a wireless networking environment, such as a high density environment. Both the detection cell and the communication cell can be set equal to each other or the detection cell and communication cell can be independently set. There are also described herein techniques for determining detection cell. Also described herein are techniques for determining communication cell. The present invention includes apparatuses configured to implement a method and/or technique described herein.
