center of gravity of the screen

uwnp.array (3,Nscreen) of floats

unitary vector along width dimension

uhnp.array (3,Nscreen) of floats

unitary vector along height dimension

wnp.array (,Nscreen)

width in meters

hnp.array (,Nscreen)

height in meters

Lshnp.array (Nseg,Nscreen,Nf)

Loss in dB to add to the FS path Loss

# geometry parametric issue : find M in [tx-rx] defined as M = alpha*rx + (1-alpha)tx where alpha in [0-1]. # if alpha = 0 then M = tx ; if alpha = 1 then M = rx. # Besides, M is defined as M = pg + beta*uw + gamma*uh then alpha*rx + (1-alpha)tx = pg + beta*uw + gamma*uh # [rx-tx , -uw, -uh]*[alpha,beta,gamma].T = pg - tx <==> Ax = b solved by la.solve ; x[0]=alpha, x[1]=beta and
