Can Amplitude–phase Imbalance Compensator of CW Doppler Radar Receiver Be Considered Indispensable?

The code not only demonstrates the design of the E2E Doppler extractor (Block 5 in the code "e2eDoppler_V3new.m"), but also validates its superior performance through ablation experiments.

Code Update Instructions
We have updated the program code and uploaded the latest version to Zenodo to resolve compatibility issues with different MATLAB versions.
If you have already downloaded the old file e2eDoppler_V3.1.m before, you only need to rename this file to run normally. For example, rename it to e2eDoppler_V3new.m.
Alternatively, you can directly download our newly updated file e2eDoppler_V3new.m from the repository to get the available program.

Update Reason
Some versions of MATLAB do not support running program files that contain the dot symbol (.) in the filename. The version number dot in the original filename e2eDoppler_V3.1.m will cause compatibility errors and prevent the program from running properly on partial MATLAB versions. This update removes the special symbol in the filename to ensure universal compatibility.
No changes have been made to the core algorithm and functional logic of the program, so the calculation accuracy and running performance remain completely consistent with the original version.
