ABSTRACT

The behavior and characteristics of waves passing through tissues (channel/medium) are useful in the development of biomedical systems for early detection and diagnosis of cancer cells or any other abruptions/abnormalities developing inside the tissues. In this paper, an adaptive filtering approach is used to model experimentally obtained values of permittivity, conductivity and scattering matrix at millimeter-wave band 50 GHz to 75 GHz, to derive channel behavior on impulse input of normal and tumor containing tissues in the skin. The adaptive filter used is recursive least square or RLS algorithm for both finite impulse response (FIR) and infinite impulse response (IIR) filter structures. The simulation and experimental results are in a good agreement with MSE of 0.0021 only.

Keywords: Channel Impulse Response, Skin Cancer, Millimeter Wave Band, RLS
