Gaussian Markov random fields (GMRFs) or Gaussian graphical models have been widely used in many applications. Efficiently drawing samples from GMRFs has been an important research problem. In this paper, we introduce the subgraph perturbation sampling algorithm, which makes use of any pre-existing tractable inference algorithm for a subgraph by perturbing this algorithm so as to yield asymptotically...
Modern advanced hardware technology has made possible the implementation of sophisticated algorithms. The Complex Block Least Mean Square (LMS) algorithm has been widely used in adaptive filtering applications. However, the major drawback of this technique is its dependence on the appropriate choice of the step size. This paper presents the Complex Block Conjugate-gradient LMS algorithm with optimal...
Wireless systems frequently employ I/Q modulation techniques to achieve spectral efficiency for high data rate applications. However, the main drawback of I/Q downconversion is the amplitude and phase imbalances between the analog components in the I and Q branches of the receiver. The resulting I/Q mismatch is unavoidable for practical quadrature receivers and can be frequency-dependent in nature...
The complex block least mean square (LMS) algorithm has been widely used in various adaptive filtering applications. However, the main drawback of the complex block LMS is its slow convergence. In this paper, a novel algorithm called complex block conjugate LMS (CBC-LMS) is presented, which incorporates the conjugate gradient principle into the complex block LMS algorithm. The proposed CBC-LMS employs...
