Hello everyone.

I am learning on how to design RF receiver along with example from this topic (Top-Down Design of an RF Receiver - MATLAB & Simulink (mathworks.com))

Anyway, On the last example Add Wideband Interference, LO Leakage, and DC Offset Cancellation.

I cannot run the simulation due to some error as shown below.

=== Simulation (Elapsed: 7 sec) ===

Warning:Warning: Noise correlation data derived from rational fit of s-parameters in block TopDownRFReceiverDesignCircuitEnvelopeWithInterferer/Circuit Envelope Model of

Direct Conversion Receiver/Sparams is not passive. These parameters are made passive for noise calculations.

Error:An error occurred in the block 'TopDownRFReceiverDesignCircuitEnvelopeWithInterferer/Wideband Interference/Sample-Rate Converter' during compile.

Caused by:

Insufficient number of outputs from right hand side of equal sign to satisfy assignment.

Per my understanding. This block is reduce number of the sample from 640 sample to 256 sample which is 2.5x downsample.

I also checked on the error block. everything seems ok.
