MultipathChannel.applyChan — Method
MultipathChannel.applyChan(in, chan::ChanPars; initialtime)

  • initialtime: Time for generating Doppler shift
source
MultipathChannel.initChan — Method
MultipathChannel.initChan(maxdoppler, samplingrate, channelmodel; rmsdelay, maxorder, gainnormalization=true)

Generate a ChanPars type channel parameters.

Arguments

  • maxdoppler: Maximum Doppler frequency (Hz)
  • samplingrate: Sampling rate (Hz)
  • channelmodel: Channel model for path delays and average path gains: supporting TDL-C, and single Rayleigh path
  • rmsdelay: Root mean square delay for TDL channel models in nano seconds
  • maxorder: Maximum filter order for FDF
  • gainnormalization: Indicator for normalizing path gains
source
MultipathChannel.ChanPars — Type
MultipathChannel.ChanPars

Type of channel parameters containing:

  • numpaths::Int: Number of paths
  • pathdelays::Vector{Float64}: Delay of each path in second. This parameter is set according to channelmodel when calling MultipathChannel.initChan.
  • averagepathgains::Vector{Float64}: Average gain of each path in dB. This parameter is set according to channelmodel when calling MultipathChannel.initChan.
  • fdfcoefs::Vector{Vector{Float64}}: Coefficients of fractional delay filter (FDF). This parameter is obtained by pathdelays.
  • nonzeroindices::Vector{Int}: Non zero index of each path for FDF. This parameter is obtained by pathdelays.
  • pathdopplers::Vector{Float64}: Doppler frequency of each path in Hz. Doppler frequency is given according to Jakes model with maxdoppler. This parameter is initialized when calling initChan.
  • fadingamplitudes::Vector{Complex{Float64}}: Instantaneous gain of each path given by Rayleigh fading. This parameter is initialized when calling initChan.
  • initialphases::Vector{Float64}: Initial phase offset of each path. This parameter is initialized when calling initChan.
  • samplingrate::Float64: Sampling rate in Hz
