Run Simulink model in Matlab for UWB channel model problem
I have been trying to use UWB Channel Model by Robert Morelos-Zaragoza
in my MATALB code for UWB system. However, when I try to use 'sim' in Matlab command it gives me following error.
>> [T,X,Y]= sim('IEEE802153a_channel_model_test.mdl',[0 1e-7],);
Warning: The discrete states in model 'IEEE802153a_channel_model_test' cannot be logged as a matrix because the model has non-double or complex discrete states. Use 'structure' format to log states (see Save Format in Configuration Parameters dialog or simset command).

I would like to get your opinion on which wireless channel model parameters
are really helpful or crucial to systems design for real system
In general, delay spread is one, so a tapped-delay channel model would
suffice. If the wireless system uses MIMO, then angular spread may also be
One could argue, however, that the needed parameters would depends on the
application. I would like to keep the discussion open. So citing system
applications, and then their crucial channel parameters as used in
simulation for the purposes of implementatio...simulink models of Earth systems

...modelling baseband channels in simulink
I'm pretty new to simulink, and I want to use it to simulate different data
coding schemes for transmission over say coax cable. I figure one of the
first things I need to do is get the frequency response of the
communications channel. Since simulink deals with samples and frames (still
not sure about the differences here), i.e. discrete time, I guess I should
sample the channel frequency response, and implement the channel as a FIR
filter? One of the things I'm unsure of is how to simulate reflections due
to impedance mismatches. Is this easy to do in simulink? And finally, ...Channel Estimation in CDMA systems
I was wondering which methods could be used to estimate the channel impulse
response in a CDMA system, where the receiver catches the superposition of
many users' signals spread with different pseudo-random codes. I would just
need the channel estimate for two of these many users and I wouldn't need
any detection of the data, I'm *only* interested in the channel estimate. A
fixed training sequence is provided.
Is there any chance of doing it at symbol rate?

In high speed link design environment, the channel models are always
given in s-parameter format.
Does anyone know a good methodology to use these measured s-parameter
data as the channel model in simulink?
If I have a impulse response of the channel, can I use that in the

Good morning fellow MATLabers...
I am doing research on PV (Photovoltaic) System Degradation on panels... I was wondering if any of you know of any Simulink library that can be downloaded or that is available to Simulate the PV Systems.
Next I was wondering if anybody can guide me on how to create my own library or modify existing libraries to do exactly what I need.

I'm trying to do run a simple model in simulink based on the results of a model created with System Identification toolbox.

From where can I get SIMULINK models for physiological systems like
body temperature control. This is for educational purpose.
