Simulink® model of a simple Bluetooth® wireless data link. Includes error correction, GFSK modulation, frequency hopping and a 100MHz channel.
NOTE: A version of this model which works with the current release of MATLAB® and Simulink® is shipped with the Communications Blockset™.

good work .. can you add input from keyboard instead of binary input and encryption and decryption with output display . this will be great

me interesa , la simulación de la version 2.0 + EDR la cual corresponde a modulaciiones pi/4 PSK y 8 DPSK, si alguien a obtenido las curvas de BER vs EbNo para estas modulaciones, se lo agradeceria.

I'm looking to simulate with the modulation types specified in Bluetooth 2.0, which are 4 and 8-ary PSK. Has anybody seen updated models to accommodate the more recent standard?

I was wondering if this model takes all the 80 Bluetooth channels into account or just 79, since the M-ary FSK [de]modulator is set by default at 79 (at least in my downloaded model). Also, wouldn't it be more appropriate to use bigger value for the second randint argument, since 100 may not be enough to spread over all the channels? I'm using 99999. Thanks a lot for the model, it is quite useful !!

In above bluetooth simulation How to analyze the signal levels in different differnt levels ( example signal between Bernouli Binary generator cyclic encoder ) . I am used scope to analyze siganl levels but it gives differnet ....differnt errors .....

If any one know how to do this pls send me a mail as soon as possiable ...

Is it possible to calculate BER vs SNR with this model. Any help will be greatly appreciated.
please mail me to pavan250@gmail.com.

Thanks

I was wondering if i could use the same program, but instead of bluetooth modulation, erform BPSK. I require frequency hopping though.

That's great ,But,How could I import this Model to Matlab/simulink function ??

because I can't open this model into the program

please tell me about this more detail information!! thanks!

I am interested in 2 problems with thismdl:
1)How can I modify the sample time for the bernoulli data source(let's say 1/50/384)because a lot of errors occurs when I do this
(and I tried in many way)
2)How can I implement multiple users but their hops to not get interference(an idea at least please)

Really great tool! I really recommend using this if your working in this area!

Very Good.
There is a need to look at power consumption however.

Great!!Very useful!!
