Detailed Description

template<class T>
class simthlib::BasebandAwgnGenerator< T >

Generic device that adds complex gaussian noise to an complex input sequence. Actually, the elements of the input and output sequence need not to be complex but must only provide a constructor that takes two double elements. (E.g. typename T::value_type val = T::value_type(1.3,1.4) )

Member Function Documentation

template<class T> static void simthlib::BasebandAwgnGenerator< T >::init (  const std::string  fileName, simth::Device **  dev, simth::DeviceSystemIntf *  sysPtr, int  ID, const std::string &  regionQualifier = "" )  [static]

Reimplemented from simthlib::NoiseGenerator.

template<class T> virtual void simthlib::BasebandAwgnGenerator< T >::print (  std::ostream &  os  )  const [virtual]

Reimplemented from simthlib::NoiseGenerator.

template<class T> virtual void simthlib::BasebandAwgnGenerator< T >::process (   )  [virtual]

Implements simth::Device.

template<class T> virtual void simthlib::BasebandAwgnGenerator< T >::setSNR (  double  snr  )  [virtual]

Sets the signal-to-noise ratio to the snr given in dB as argument. Hence, the linear signal-to-noise ratio is computed by 10^(snr/10). Since the noise power per quadrature component is assumed to be 0.5, the noise power is computed by snrLin*0.5 where snrLin is the linear signal-to-noise ratio. Implements simthlib::NoiseGenerator.
