error

Block ‘ofdm_fdm/Buffer’ uses the frame status of the signal. Update your model to move control of sample-based and frame-based processing from the frame status of the signal to the block dialog parameters. For help in resolving this and other upgrade issues, run the ‘Check model for block upgrade issues requiring compile time information’ check in the Simulink Upgrade Advisor.

To identify user-created library blocks with frame upgrade issues, run the ‘Check model for custom library blocks that rely on frame status of the signal’ check in the Upgrade Advisor.

For general information about the changes to frame-based processing, see your product-specific Release Notes.

solved

chang “treat mx1 and unoriented sample-based signals as” choose “one channel”
