Next let's try a raised cosine (RC) pulse （升余弦）with 30% excess bandwidth.* |$ L" M' H6 `8 V3 H
Copy the RC Pulse program called "rcpuls" on page 23 of the Anderson text into a file called "rcpuls.m". Or cut and paste from here...- O' N, n) D) [, B* q% ?7 S7 v( J7 i
function y = rcpuls(a,t)tau = 1; % Set the symbol timet = t + 10^(-7); % This avoids dividing by zerotpi = pi/tau; atpi = tpi*a;at = 4*a^2/tau^2;y = sin(tpi*t).*cos(atpi*t)./(tpi*t.*(1-at*t.^2));: k( C2 ]; A1 h7 A9 L- w
Now create an RC pulse by entering the following at the Matlab prompt.: E4 L0 p/ c0 m7 b
rcpulse = rcpuls(.3,[-6:0.01:6]); |
