function linkpar=linkparset(varargin)
%LINKPARSET Link parameter configuration for WIM
%   LINKPAR=LINKPARSET(K) is a struct consisting of randomly generated link
%   parameters for K links. LINKPAR=LINKPARSET(K,RMAX) uses cell radius
%   RMAX for generation of MS-BS distances (default: 100 meters).
%
%   LINKPAR=LINKPARSET(...,SEED) sets the random seed used in link
%   parameter generation. 
%
%   The parameters and their defaults are:
%
%   MsBsDistance    - see below
%   ThetaBs         - U(-180,180) degrees, U denotes uniform pdf
%   ThetaMs         - U(-180,180) degrees
%   MsVelocity      - 10 meters per second 
%   MsDirection     - U(-180,180) degrees with respect to broadside
%   StreetWidth     - 25 meters
%   Dist2           - NaN default -> will be drawn randomly
%
%   See [2, Fig. 5.2].
%
%   The pdf of the random variable (RV) MsBsDistance is R+RMIN, where R is
%   an RV with pdf p(r)=2*r/r0^2, where r0 defaults to (RMAX-RMIN) meters.
%   Hence, MsBsDistance is an RV such that users are approximately
%   uniformly distributed in a circular disk over [RMIN,RMAX] meters. Default
%   values for RMIN and RMAX are 5 and 100 m respectively. For usability,
%   the same default is used for all scenarios.
%   
%   Some notes about the parameters:
%
%   - StreetWidth, this is utilized only with path loss model in [1, sec 5.4.1.2]
%   - Dist2 is defined in [1, Figure 5.16] and generated randomly if empty
