function [Lam,lam,Gam,gam,nlos,sdi,sdc,sdr]=UWB_params(cm)
% S-V model parameters for standard UWB channel models
% Input
%   cm=1 : based on TDC measurements for LOS 0-4m
%   cm=2 : based on TDC measurements for NLOS 0-4m
%   cm=3 : based on TDC measurements for NLOS 4-10m
%   cm=4 : 25 nsec RMS delay spread bad multipath channel
% Output
%   Lam  : Cluster arrival rate (clusters per nsec)
%   lam  : Ray arrival rate (rays per nsec)
%   Gam  : Cluster decay factor (time constant, nsec)
%   gam  : Ray decay factor (time constant, nsec)
%   nlos : Flag for non line of sight channel
%   sdi  : Standard deviation of log-normal shadowing of entire impulse response
%   sdc  : Standard deviation of log-normal variable for cluster fading
%   sdr  : Standard deviation of log-normal variable for ray fading
