Complex independent component analysis (ICA) has found utility in separation of complex-valued signals such as communications, functional magnetic resonance imaging, and frequency-domain speeches. However, permutation ambiguity is a main problem of complex ICA for order-sensitive applications, e.g., frequency-domain speech separation. This paper proposes a semi-blind complex ICA algorithm based on...
SiGe based metal-oxide-semiconductor field-effect transistors (MOSFETs) were fabricated, in which the SiGe channel layer was deposited by using laser-assisted plasma-enhanced chemical vapor deposition (LAPECVD) system. The characteristics were compared with the device without laser assistance.
