  • Patent number: 7245588
    Abstract: A WLAN (Wireless Local Area Network) receiver is provided that has a power normalization unit that receives an input signal having a signal power within a given power range. The power normalization unit outputs a signal that is derived from the input signal by applying one of at least two different power normalization functions to the input signal. The power normalization unit comprises a power determination unit for determining the signal power, and a function selection unit for determining one of at least two subranges of the power range. The determined subrange includes the signal power. The function selection unit is further arranged for selecting one of the power normalization functions dependent on the determined subrange. By subdividing the power range and applying power normalization functions dependent on the respective subrange, simplified circuitry may be used by avoiding the calculation of the reciprocal square root function.
