Generalized optimal thresholding for biometric key generation using face images
1 In this paper, we study biometric key generation using face images. Given a face image, a set of biometric features are extracted. Each feature is compared with a threshold to ge...

MIMO transceivers with decision feedback and bit loading: theory and optimization
This paper considers MIMO transceivers with linear precoders and decision feedback equalizers (DFEs), with bit allocation at the transmitter. Zero-forcing (ZF) is assumed. Consider...

Closed-Form Exact BER and Optimization of Generalized Orthogonal STBCs
Abstract--The closed-form exact bit error rate (BER) expressions of generalized orthogonal space-time block codes (OSTBCs) are first derived for quadrature amplitude modulation (QA...
