SNR Maximization at CSI Aware AF Relay
This paper concerns two-hop communication over relay-assisted Block fading channel. It is assumed there is not a direct link between the transmitter and the affiliated destination and the communication occurs in two hops through the use of a relay, where the amplify and forward (AF) strategy is employed at this node. In this case, in a Rayleigh block fading channel, the optimal weight function ...
متن کاملSNR Maximization Hashing.dvi
We propose a novel robust hashing algorithm based on signal-to-noise ratio (SNR) maximization to learn compact binary codes, where the SNR metric is used to select a set of projection directions, and one hash bit is extracted from each projection direction. We first motivate this approach under a Gaussian model for the underlying signals, in which case maximizing SNR is equivalent to minimizing...
متن کاملSNR lidar signal improovement by adaptive tecniques
were P(t) is lidar observation after deconvolution process, strongly dependent on geometrical and optical characteristics of the sensor, and Pδ(t) is ideal observation when the response funtion of lidar sensor is a Diràc distribution, like ideal laser pulse. From (1), the additive noise term N(t) makes a direct deconvolution impossible. In general, deconvolution process with R(t) show a low-pas...
متن کاملSpeech Signal Enhancement Using Firefly Optimization Algorithm
The speech signal enhancement is essential to obtain clean speech signal from noisy signal. For multimodal optimization, the natural-inspired algorithms such as Firefly Algorithm (FA) are better. The proposed algorithm contains preprocessing module, optimization module and spectral filtering module. Here, Loizou’s and Aurora databases are considered for signals. In this paper the Perceptional E...
