BPSK receiver simulation using Spread Spectrum Techniques

BPSK receiver performance using DSSS in presence of AWGN+Rayleigh Fading.

Description

This is a code for simulation of BPSK receiver using Direct Sequence Spread Spectrum. The performance is evaluated in presence of AWGN and Rayleigh fading.Jakes' Model has been used to obtained coefficients for rayleigh fading.

The file when downloaded does not contain the BPSK Rx simulation...only the rayleigh fading simulation?

[Jerry Jerry]

i think there is something wrong in the source code when adding rayleigh fading coefficents. after uncommenting this segment,
the k is always equal to 1, and only the magT(1,1) was add to the modulated signal

Hello Abhijit,

dont know if my email reached u...hence...

Could you please tell me why did u take the integer in rand('state',12345) and randn('state',54321) to be so? In general, how does one decide for an application?

I wud be grateful for your help.
thanks in advance.

forgot to add my [e-mail]

[arun s.]

sorry for bothering again...
This is regarding the SNR equation in the awgn(msg,'snr') option. Is that a standardized formula? If not, then how did reach it?
Thanks again.
arun.

Hi Abhijit, very useful info there. Btw, I have a question here. In your codes, the line below adds awgn to the signal. Is there any way to know what the 'measured' signal power value is?
   % ADDING AWGN TO THE SIGNAL
    msg_rx_data=awgn(msg_tx,SNR-10*log10(N),'measured','dB');

Iwant to simulate the transmitter and reciver of BPSK DSSS

[adem bedru]

I need the complete matlab code for simulation of BPSK +DSSS.
      thanks!

[rebecca ma]

hi i sent u an email asking some qns abt ur code. can u pls clear my doubts and reply? thanks!

[ashu meku]

would you please help me about matlab programs(codes)used to generate PN seequences and know the perforance of DSSS.
thank you!

can you offer the demodulation code?

[Huy Nguyen]

 would you please help me about matlab programs(codes)used to generate PN seequences and synchronous PN in DSSS.

[Trung Tran]

 would you please help me about matlab programs(codes)used to synchronous PN in DSSS. It's really a problem to me. Thank you!

Can you please help me with a MATLAB program for calculation bit-error rates in Uncoded BPSK and Coded BPSK system

[Frank Nnadi]

can you please help me with a MATLAB program for calculating bit-error rates in both uncoded BPSK and coded BPSK systems. Thanks

Hello,

Thank you for the simulation. one problem ther is no BER_RAY Varible and the parameter T at the BER Code is not defined.

[ravi kiran]

can u help me for material on BPSK transceivers..
