UWB Fixed-Point Model (Multiband OFDM)

Ultrawideband (UWB) multiband OFDM physical layer with fixed-point transmitter/receiver modeling.

Description

* Based on IEEE 802.15.3a multiband OFDM proposal (Sept 2003 version)
* End-to-end physical layer (streaming mode)
* Highest mandatory data rate (200 Mb/s)
* QPSK modulation, rate-5/8 forward error correction coding (convolutional + puncturing)
* OFDM transmission: 122 subcarriers, 22 pilots, 128-pt FFTs, zero prefix, guard period
* Fixed-point model of OFDM TX/RX (16-, 12-, 10-, and 8-bit)
* 2x spreading across sub-bands
* Data interleaving
* PLCP preamble (packet sync, frame sync, and channel estimation)
* Viterbi decoding
* Mode 1 frequency hopping (3 bands)
* Includes channel model used in IEEE 802.15.3a group.

Instructions:

1. Unzip/copy all files into a writable folder.
2. Start MATLAB, either R13 SP1 (v6.5.1) or R14 (v7.0).
3. Change directory to above folder.
4. Change subdirectory to either r13sp1 (for MATLAB v6.5.1) or r14 (for MATLAB v7.0).
5. Open uwb.mdl (double click on file in Current Directory pane).
6. The first time the model runs, it will automatically generate four .mat files. (These channel model files are required to run the model.)

Hi,
1) Thank you for sharing it to us. Your work is awesome!
2) Would you kindly send the documentation to me? It would be a great help! My email: [e-mail]
3) Is there any possibility I can change the UWB TxRx model of this program? E.g. Add some channel estimation algorithms in Rx or try some cooperating schemes there, ...etc.

Thank you .

[Emdad BoZZ]

Ppl having these two errors:
1. Reference to non-existent field 'comm'.
2. Error in 'uwb/Scopes': Initialization commands cannot be evaluated.

I used Matlab 7.8 R2009b and solved this issue.

Try this:
1) Make sure you have the required packages mentioned by author.
2) Use the RS13SP2 folder's content.
3) open uwb.mdl in matlab
4) type slupdate('uwb') in cmd window.
5) run simulation

[Sayeed Islam]

Well done. I am working on UWB-OFDM now.
would you kindly send me the doc. of the program at my email [e-mail] . Thanks

[Mosab El-Dramly]

I use matlab 7.8.0 (R2009a), similarly as Avihay and Devil, I'm facing two errors

i use matlab 2009b. like Avihay, i also have trouble with these two errrors. i tried using the command slupdate but i can't solve the problems. anyone could help me? s

[Kane]

Very good simulation. What is the approach to channel estimation of this one?

[Avihay Shemesh]

thanks Sid.
I tried this option before but after I slupdate('uwb') I had the same 2 errors, any idea?

[siddharth Shetty]

Reference: My comment on 20 Jul 2009.

I updated the Simulink files using command SLUPDATE... this solved my problem....

[Avihay Shemesh]

Hi, it seems there is a problem with MATLAB verion 7.7 (R2008b). running the model causes 2 error:
Reference to non-existent field 'comm'.
Error in 'uwb/Scopes': Initialization commands cannot be evaluated

I saw this is a known issue (Sid, 20 Jul 2009). can anyone help with this?

I am currently doing a thesis about UWB OFDM, this system helps me a lot, but can you please send me some documentation with explaination of this system or the webinar, because the webinar is missing..

and could you give me some explanation about the error, says one error(Parameter 'Indices' specified in 'uwb/Scopes/Signal Constellation/Reshape Data/Remove DC component and pilots and CE seq' provides index elements for 1 dimensions. It does not match the number of input dimensions, 2.) can you please send me some documentation with explaination of this system.

thank you.

[pedro roig]

i'm working on uwb now and i'd really appreciate if you could send me the documentation. great job!!!

[kai shi]

The channel model realized in uwb_imr.m may be incorrect!!!

1) Given the fact that the sampling frequency of simulated system 528*6 MHz and
the channel model is derived from 802.15.3a's real wideband model (from DC to 6GHz), the correct procedure to generate
complex baseband model should be downconversion-> lowpass filtering
instead of lowpassfiltering-> upconversion.
2) Normalization is applied in original model. So there is no fading anymore? (since each realization has the same overall energy). Normalization may necessary after lowpass filtering, but the property of fading should be kept.
