Description

The IEEE Multipath Channel block simulates an indoor UWB channel as described in "A Channel Model for Ultrawideband Indoor Communications" by J.R. Foerster, M. Pendergrass and A.F. Molisch, November 2003, and attempts to incorporate the processes used in their MATLAB scripts.

The discrete input is convolved with a realization of the channel impulse response. This response can be one of 4 types (CM1, CM2, CM3 or CM4) described in the paper or a custom channel with user-defined parameters. Response terms that extend beyond one symbol period (ISI) are added to the output for the next symbol period.

Sample time is the rate at which the discrete signal is processed through the channel. It represents the time resolution of the channel and is entered in nsec. The symbol period is the time period of each data symbol and is entered as an integral number of sample times. For example, enter
Sample Time: 0.02
Symbol Period: 100
for a signal with a symbol period of 2 nsec. and a sampling period of 20 psec. Symbols per fade refers to the number of symbol periods over which the channel does not change.

Channel choices are
CM1 IEEE line of sight, < 4m
CM2 IEEE non-line of sight, < 4m
CM3 IEEE non-line of sight, 4-10m
CM4 IEEE strong dispersion, delay spread of 25 nsec.
custom define parameters manually

Useful. does it still work for 0.1m between RX/TX?

Hi, I don't know how to get the channel coefficients vector?

Hi im doing my final proyect of a UWB model and i need information about channel and single band model, maybe u can share some.
Thank and excelent job

I have a DS-UWB simulation which was written completely in m-file, I can't use your model in my simulation instead of three paths channel model which I proposed in my simulation.
