Constant Modulus Beamforming testbench in Simulink

Hello,

I am trying to create a virtual test bench (Receiver) for Constant modulus beamforming algorithm. Test bench includes all the parts of receiver required for CM beamforming: RF receiver, BPF, IF down corverter, IF BPF, ADC, IQ Demodulator and then CM beamformer. How can I do that in Simulink?

How to interface all the parts? I am stucked at the narrowband RX array. After the receiver output how I can feed it into bandpass filter? Because receiver output is MxL array, each column is a signal for each antenna. Do I need to use separate BPF block for that? Or one BPF block can do the work?

Is there any model in simulink for cormercial DSP kits?

What is the best way to prepare this virtual test bench? Can you give any example? I looke at the availabe beamforming in matlab, they don't include CM. And also there model is quite different form the required models for CM which I found in the literature.
