% % FUNCTION 8.1 : "cp0801_pathloss" % % Attenuates the input signal 'tx' according to % the distance 'd' [m], the decaying factor 'gamma' % and the constant term 'c0', which represents the % reference attenuation at 1 meter. % % The function returns the attenuated signal 'rx' % and the value of the channel gain 'attn' % % Programmed by Guerino Giancola % function [rx,attn] = cp0801_pathloss(tx,c0,d,gamma) % ------------------------------- % Step One - Path loss evaluation % ------------------------------- attn = (c0/sqrt(d^gamma)); rx = attn .* tx;
