摘要： A method and system for estimating noise variance. A method for noise variance estimation comprises receiving a first multi-sample symbol and receiving a second multi-sample symbol. The first multi-sample symbol is subtracted from the second multi-sample symbol to produce a set of noise samples. The set of noise samples is used to produce a noise variance estimate. The noise variance estimate is applied in various tasks (e.g. channel estimation, log-likelihood ratio computation, and/or minimum mean squared error equalization) to process data provided to a user.

摘要： The distance between a first Multi Band Orthogonal Frequency Division Multiplex (MB-OFDM) data transceiver and a second or more such transceiver is determined using known techniques. The radio frequency path loss between transceivers is estimated given said distance, using a known relationship between distance and path loss, and further accounting for line-of-sight or non-line-of-sight conditions if desired. This path loss value is added to the typically minimum transmit power level, absent path loss, needed for reliable data communication. This modified initial transmit power level is then used by the first transceiver to begin the known iterative feedback process of transmit power control (TPC). Because this modified initial transmit power level, based on distance, is closer to the final optimum level, convergence in the TPC process occurs in fewer steps and less time than had the initial transmit power been maximum power as is typical in known TPC systems.
摘要翻译：使用已知技术确定第一多频带正交频分复用（MB-OFDM）数据收发机与第二或更多个这样的收发机之间的距离。使用距离和路径损耗之间的已知关系，给出所述距离估计收发器之间的射频路径损耗，并且如果需要，进一步考虑视线或非视距条件。该路径损耗值被添加到可靠数据通信所需的通常最小发射功率电平，不存在路径损耗。该修改的初始发射功率电平然后由第一收发器用于开始已知的发射功率控制（TPC）的迭代反馈处理。由于这种基于距离的修改的初始发射功率电平更接近于最终的最优电平，所以在已知TPC系统中典型的情况下，TPC过程中的收敛在比初始发射功率达到最大功率的步骤少，时间更短的时间内发生。

摘要： Disclosed herein is a system and method for determining the presence of rotated-BPSK modulation. In addition, disclosed herein is a system and method for determining if a received packet is a Legacy, Mixed-Mode, or Green-Field packet in accordance with the determination of the presence of rotated-BPSK modulation. The presence of a Green-Field packet may be determined by detecting if additional tones are being excited in an LTF symbol of the received packet and/or if a SIG field symbol following the LTF symbol is modulated by rotated-BPSK. The presence of a Mixed-Mode packet may be determined by detecting if the first four bits of the SIG field symbol following the LTF symbol are [1 1 0 1] and/or detecting if a symbol following an L-SIG symbol is modulated by rotated-BPSK. The presence of a Legacy packet may be determined by detecting if the symbol following the L-SIG symbol is modulated by BPSK.
