FPGA Central

hallo

I make some study on Adaptive CDMA (adapting processing gain).
adapting PG according to channel sate (poor, medium, worse)

that 's why I want to know the influence of channel on the transmitted
signal according to Processing gain.


thus, I need a channel model (Rician or rayleigh) with input
- K-factor, rms delay spread in case of Rician
or
- dopler frequency in case of rayleigh.

Please : has anyone a simulation written in matlab (m-file) that
generate
multipath fading as I descibe.

[multipath] = rician(K, rms_delay)
or
[multipath] = rayleigh(fd)
or any idea how to loss my problem

thanks a lot
