  fixed bandwidth
One way to achieve a range of data rates with fixed bandwidth is to allow the use of different processing gains.
      
The resources we consider are: fixed bandwidth available for each user and the transmit power budget for each cell.
      
The FPT is also distinguished from other competitive parametric methods, which are generally unstable as a function of signal length N at a fixed bandwidth and, therefore, particularly unsuitable to clinical data.
      
This fixed bandwidth overcomes the curse of dimensionality that typically plagues density estimation in high dimension.
      
In addition, because the approximate likelihoods are only used to rank the observations, they can be derived from a density estimate using a fixed bandwidth.
