seed parameter for WLAN Channel Model

Question asked by pfm on Jun 13, 2007
Latest reply on Jun 14, 2007 by pfm
I am making simulation in order to haver BER curves in function of Eb/No for WLAN transmission under multipath propagation condition.
1000 frames of 8000 bit are emitted to compute a BER value for a given Eb/No

Using WLAN_ChannelModel, i don't understand how to introduce fast fading in my simulation.
If the seed parameter in the WLAN_Channel is constant, the received signal power at the input of the receiver is quite constant (only 1 dB of variation) during the 1000 frame.

That is why I would like to know how I can modify the seed paramater for each frame transmission.

If the seed parameter in the DF component is equal to 0, a randomly seed is chosen at the begining of each simulation. But how can I make it change during a simulation ?

thank you for your help
