Dear All

need help in DPSK matlab code. i want to implement dpsk modulation technique, if anyone have the matlab code for this modulation please send it.

your early response will be highly appreciated.

Thanks in advance

regards,

Rao
 

see your PM as i sent to you a message also see the mathwork file central for more help
 

Hi all!!

I just found out this site!! It's great!!

I am also having trouble in dpsk modulation code. Could someone send me the code or some hints?

Thanks!!
 

Thanks ux for your help!!

Do you by any chance have the code also to do the dpsk modulation without using the simulink?

see this matlab help:
---------------------------
dpskmod

Differential phase shift keying modulation
Syntax

y = dpskmod(x,M)
y = dpskmod(x,M,phaserot)
y = dpskmod(x,M,phaserot,symbol_order)
_______________________________________

Examples

The example below plots the output of the dpskmod function. The image shows the possible transitions from each symbol in the DPSK signal constellation to the next symbol.

M = 4; % Use DQPSK in this example, so M is 4.
x = randint(500,1,M,13); % Random data
y = dpskmod(x,M,pi/8); % Modulate using a nonzero initial phase.
plot(y) % Plot all points, using lines to connect them.

best regards
