Abstract
Apparatus and methods are disclosed for determining, on a small form factor 5G communication device, the range of a target object include receiving, at a receiving antenna of the small form factor communication device, a composite signal where the composite signal includes a target reflection signal and a mutual coupling (MC) leakage signal, generating a composite beat waveform by mixing the composite signal with an original signal, where the composite beat includes target beat and MC leakage beat waveform components, isolating the target beat waveform by subtracting from the composite beat waveform a weighted, k-delayed composite beat waveform, where for a configured k the target beat waveforms are uncorrelated and the MC leakage beat waveforms are correlated, and determining, using the target beat waveform, a range of the target object from the small form factor device.
