Hello

I construct a multipath channel

first i generate a Discrete pulse, then pass it through a raised cosin e transmit filter, and then pass through multipath rayleigh channel .

but error occurs in simulink:

Complex signal mismatch. Output port 1 of 'c/Multipath Rayleigh Fading Channel' is a signal of numeric type complex. However, it is driving a signal of numeric type real

you have a problem with the types of the data. The type of the first data (the Output of of /Multipath Rayleigh Fading Channel') is complex and you need to be real. Use the convert bloq to convert to type real.

hi andoni im getting this error "Complex signal mismatch. Input port 1 of 'pv_module_solarex_temp/Mux' expects a signal of numeric type real. However, it is driven by a signal of numeric type complex"

how do i resolve this error,any suggestions would be helpful

Hi, may I know if anyone has found a solution for this problem please? I could not apply the multipath channel in my model because of the same error message "complex signal mismatch". I've used the signal specification block but the problem is still.
