polarity signal transmitter separated ?

I want to separate the negative signal from the positive signal?

x=41 ; %number of pn

pn= [10 -5 4 - 8 10 8 9 6 -7 - 9 7 - 6 5 6 -4 2 -3 -4 5 -7 -6 -8 9 4 11 -8 -5 6 -4 -7 -8 9 7 6 3 2 4 5 6 8 7 9 -5 -9 8 -5 7 ];

xp=pn(pn>0); % positive signal

xn=pn(pn<0); % negative signal

Xn=abs(Xn); % absolute

I want to set a break between positive and negative signals by (x /4).

i:e

d=(x/4);

xv= xn+d % d is the delay

I also want to trace the length of both positive and negative signals to be able to decode the code again.

tx=[xp,xv] %transmit signal

Seems like you're doing that. I'm not sure what the question is, if any, in the "I want..." announcements.
