Baseband Noise Suppression in Ofdm Using Kalman Filter

Description: As the technology is advances the reduced size of hardware gives rise to an additive 1/f baseband noise. This additive 1/f noise is a system noise generated due to miniaturization of hardware and affects the lower frequencies. Though 1/f noise does not show much effect in wide band channels because of its nature to affect only certain frequencies, 1/f noise becomes a prominent in OFDM communication systems where narrow band channels are used. in this thesis, I study the effects of 1/f noise on … more

Behavioral Aspects of Latino Familialism: a Three Study Analysis

Description: The existing research on Latino familialism draws a distinction between the attitudes associated with familialism and familialism-based action. Because attitudes tend to be more stable when considering variables such as immigration generation status, etc., social science researchers tend to employ measures based on attitudinal aspects of familialism, rather than action or behavior. Because of this preference, there is a lack of studies that examine familialism-based action and behaviors. This d… more
