HEC in Bluetooth
Hany - 2006-12-25 16:27:00
Dear All,
I'm working since a while on the implementation of the Bluetooth
baseband functions on a SW code.
To get directly to the point : If you check the blueooth standard
V.2.0+EDR page (89...Channel models for HIPERLAN/2 ETSI/BRAN Doc.
Hany - 2006-10-11 07:48:00
Dear All,
Can somebody help me in finding the following documents?
1. J. Medbo and P. Schramm, "Channel models for HIPERLAN/2,"
ETSI/BRAN
document no. 3ERI085B.
2. J. Medbo and J-E. Berg, "...Rayleigh Channel for HIPERLAN2 simulations
Hany - 2006-09-13 04:47:00
Dear All,
I used to simulate the OFDM chain of HIPERLAN/2 in a multi-path
channel.
The channel model I used is a tap-delay fixed model of 8 paths. Each
path, has a fixed attenuation and fixed dela...Re: OFDM cyclic prefix/Equalization question
Hany - 2006-08-06 04:06:00
Hello,
In order to check the effect of the CP, you take two values of CP one
less than the max delay of your muli-path channel and othe other CP is
greater then this delay...
When the CP is le...LMMSE estimation
Hany - 2006-06-14 11:44:00
Hello ALL,
I'm trying to simulate a LMMSE equalizer for OFDM signal.
The general equation requires the calculation of (X.X^H) where X is
the transmitted signal OR > > -----> X is the diagona...Re: cyclic prefix in OFDM and precursor ISI
Hany - 2006-03-09 02:44:00
Due to multi-path channel effect, multiple copies of the signal reaches
the receiver with different delayes which causes ISI.
Normaly the subcarriers in OFDM symbol are orthogonal or ( they have

It's very hard to say that there is a significant or dominant block for
the system..
It's quite complecated complete system in whcih you can notice that all
the blocks are hardly needed.
Maybe t...Whitening in Bluetooth
Hany - 2006-03-06 12:47:00
Dear All,
The whitening word " in the bluetooth standard" is generated with the
polynomial
g(D) = D^7 + D^4 + 1. Also the circuit is represented in the standard
whcih is saying that the shift r...SYNC_WORD generator
Hany - 2006-03-05 07:17:00
I'm trying to build a bluetooth simulator with M-files and I'm now
writting the part concerning the BCH (64,30) code which is generated
using a certain polynomial (specified in the standard, but the...
