... earlier. In previous work, we introduced Gaussian processes for machine learning as a novel nonlinear tool for designing digital communication receivers. Gaussian processes can be applied to regression ... we use both settings for tuning digital communication receivers with short training sequences. We compare Gaussian processes for regression (GPR) and Gauss...

... the battery life. Building separate transceivers for individual modes of operation is a straightforward task, and it provides the best performance for each mode, but on the other hand, it significantly ... z Q (t)sig- nals (ρ cos(φ)andρ sin(φ)) are digital. Therefore, as shown in Figure 1, two Digital- to-Analog Converters (DACs) need to be employed before the upconversion stage. The sam...

For low SNRs, the dereverberation ... curves for speech enhancement with blind RT estimation are almost identical to those obtained by using the actual RT. (Using other RIRs and noise sequences led to the same results.)...
