Re: stds-802-16-mobile: Channel Model
Dear Russell McKown
thank you, but in the recommendations ITU and ETSI reported in IEEE
802.16e-03/01 "low level" channel models are described.
Could you tell me how are you using these channel models to estimate
the performance of the high levels of network architecture (Mobility
Agent, ATM, IP ... TCP, application protocols, ...)?
Best regards.

PS: I've did some calculations about the coherent band of 802.16e channel
(I've based on the ETSI vehicular test environment) and I've understood
that each sub-channel is a frequency-selective channel too. I'm
sorry.

Dear members,
I'm studying a channel model for 802.16e. I'd like to know if it is
correct
to assume that each sub-channel is a "not frequency-selective"
channel
(even if the whole channel is a "frequency-selective" channel).
I suppose
it is possible to model each sub-channel with an (simple) independent
channel model (from adjacent and other sub-channel) using large guard
bands
between the sub-channels.
Comments and suggestions are well wanted.
Best regards.
