Simulink® model of a Bluetooth® communication link transmitting HV1, HV2 or HV3 voice packets.
NOTE: A version of this model which works with the current release of MATLAB® and Simulink® is shipped with the Communications Blockset™.
The model includes wave file I/O, CVSD speech coding, HEC, FEC, framing, GFSK Modulation, frequency hopping, and an 802.11b interferer.
Instructions: Unzip to a new folder, change the MATLAB current directory to this folder, then open the 'bluetooth_voice' mdl file.
'bluetooth_voice_article.mdl' is previous version of model which only does HV3 and is described in word document.
Hello, I got the following error while running the model.
Error in 'bluetooth_voice_article/Master Transmitter (Cellphone)/Hop Sequence Generator/Random White Hop Sequence/Frequency hopping code 1//1600 sec (page 127)'. Initialization commands cannot be evaluated. Can you please suggest me how to solve the above error..
THere are some errors during operating this syetem that I can not solve.
Error in 'bluetooth_voice_article/Master Transmitter (Cellphone)/Hop Sequence Generator/Random White Hop Sequence/Frequency hopping code 1//1600 sec (page 127)': Initialization commands cannot be evaluated. MATLAB error message: Index exceeds matrix dimensions.
I'm a 2nd year computer science student at the University of Nairobi (UoN). I'm currently interested in a project about Bluetooth voice transmitting. My argument is, 'If my friend is in the next room and I want to ask him something, why call him while we can just talk cheaply through Bluetooth?' So guys, please assist me how to go about this coz I've just started the research.
Thanks in advance.
this excellent work done by you. but can please give detial description of this model i would like to know about the design and how did u make this model in detail in simulink becoz i am looking for ward this type of models in simulink hope u will reply soon to my email address:firstname.lastname@example.org or in mathsworks only
This model was only tested with the MATLAB release listed above (7.0.1) and a few others. A version of this model which works with the current release of MATLAB and Simulink is shipped with the Communications Blockset called commbluetoothvoice.mdl
Enter at the command line:
I am also having trouble running this demo. It fails every time. Is there an updated simulation that works?
Thank you very much
I tried to run bluetooth voice model in Matlab's demos.
But, fail. Does somebody run successful for the demos at R13-SP1?
how to fix to make the simulation runnable?
Dear sir, this is extremly interesting. i was wondering if you could explain to me in detail what is happpening here. im a 4th year honours student at glasgow caledonian university astudying telecommunications engineering and this is relative to my project. this would be much appreciated. thank you
in fact, i am not qualified to rate your research but i am studying electronics engineering in Albalqa Applied Univrsity in Jordan and i am agreat admirer of your acheivements and i would be grate full if you e-mail me
i appreciate you!
i would information about jpeg2000
wonderful work needs to be expanded as state machine
very good for your project we are bhargav,naveen and lakshminarayanan
Dear sir, Im very interisting about your bluetooth transmition.Can you explain about the communication link between transmitter and receiver for voice.
A small demo nearby could draw in more readers and give some insight for the newbies who r interested like Nanda, Mudumba and many more.

I am very much interested in this Bluetooth technology using frequency hopping spread spectrum, so can u expalin in detail with the simulation model.
i would be very much grateful to you.
Hav u tried demodulating the bluetooth physcical layer information? I am trying to build a bluetooth transceiver in software.
I would appreciate any help you vcan extend!
I would like to ask
how to set the trasmission to be 1 Mbps?
is it the sample time? As I saw you set the sample time to be 1.5e-6
then 1Mbps = 15 / 1.5e-6???
Im very interisting about your bluetooth transmition.Can you explain about the demodulation and frequency hoping receiver. Why delay must be 55 and filter,conjugate

please send M code to run simulation and generate BER Vs hop frequency
The CVSD block (Encoder/Decoder) doesn't work according to the Bluetooth spec., otherwise, it looks pretty neat.
For more information you can contact me.
Removed word doc.
Fix link formatting.
Add note saying that a version which works with the current release of MATLAB/Simulink is shipped with the Communications Blockset.
Update to R14. Still contains R12.1 version.
Updated URL in description.
Corrected transmit power by changing dB attenuation value. Previous model's transit power was 10dB too high, so the true Eb/No was 10dB higher than was specified.
Added HV1 and HV2 packet types and transit slot option. Added legend to timing diagram to mark each slot and every 6th slot. Added sample-time legend, useful when sample-time colors is selected. Moved BER meters to inside receiver.
Added connection state hop sequence option to hop generator. Placed 802.11b interferer, hop generator and bluetooth clock in seperate library 'bluetooth_lib'. Added link to on-line description of model.
Corrected time scale in timing-diagram scope. Added additional instructions to run model.
Correct word document.
Correct mistake in word document.
