Property Detail

• boolean fastFading

  Controls fast vs slow fading.

• float pfa

  Acceptable probability of false alarm for packet detection.

• float processingGain

  Processing gain (or loss) in dB, to cater for effects such as coding, coherent use of multipath in equalization, poor synchronization, etc.

• float ricianK

  Rician specular component (parameter K). A low value of K less makes the channel similar to a Rayleigh fading channel, while a high value of K makes the channel an AWGN channel.

Constructor Detail

• BPSKFadingModel(AbstractAcousticChannel parent)

  Creates the communication model.

Method Detail

• int decode(Reception rx, double snr)

  Simulates bit errors in the received frame.

  Parameters:

  rx - details of the reception

  snr - signal-to-noise ratio

  Returns:

  number of bit errors

• boolean detect(Reception rx, double snr)

  Simulates preamble detection (assuming pulse compression).

  Parameters:

  rx - details of the reception

  snr - signal-to-noise ratio

  Returns:

  true if detected, false otherwise

• void setPfa(float p)

  Set acceptable probability of false alarm for preamble detection.

  Parameters:

  p - probability of false alarm

• void setRicianK(float k)

  Set Rician specular component (parameter K). A low value of K less makes the channel similar to a Rayleigh fading channel, while a high value of K makes the channel an AWGN channel.

  Parameters:

  k - Rician K parameter
