We give an algorithm for the single-stage maximization criterion to attain multichannel blind deconvolution. This criterion determines the coefficients of equalizers for all channels simultaneously. However, the original maximization criterion has many constrains so that it is difficult to directly implement it as a numerical algorithm. By exploiting pre-whitening and lattice representations of paraunitary systems, we can reduce the original maximization problem into a simple constraint-free one and then present a stochastic gradient algorithm.
A quadrotor is one of Unmanned Aerial Vehicle that has a capability to flight in the restricted area. Quadrotor as the flying robot attracted the interest from various groups such as researchers, hobbyists, and milita...

A number of methods have been presented to calculate the worst case execution time (WCET) of real-time programs. However, to properly handle semantic dependencies, which in most cases is needed to reduce overestimation, all these methods require extra semantic information to be given by the programmer (manual annotations for paths, loops and recursion dept.). To manually derive these annotations is often difficult and the process is error-prone. In this paper we present a new method to automatically derive safe and tight annotations for paths and loops. We illustrate our method by giving some examples and by presenting a prototype tool, implementing the method for a subset of C.
A well-performing double-talk detection (DTD) algorithm is a vital part of an acoustic echo canceller. However, recent algorithms are typically evaluated using a static time-invariant room acoustic impulse response, o...
