The area of Multiple Input Multiple Output (MIMO) communications systems has received enormous attention recently as they can provide a roughly linear increase in data rate by using multiple transmit and receive antennas. MIMO combined with an Turbo coding has been shown as a promising way to achieve near capacity for wireless channels. This paper proposes applying an Asterism based decoder to produce an additional multi user access scheme on top of the primary access method for Ad Hoc networks. After reviewing Sphere and Asterism decoding for MIMO systems with a larger number of transmit than receive antennas, this paper …

In many welding applications, programming time has been the biggest obstacle for the widespread acceptance of robots, impeding the advancement of this technology and limiting it to medium or large batch applications. In particular, for repair of worn components where the damage is irregular, reprogramming by skilled personnel is required at added cost and time. This paper outlines a novel offline programming technique which allows robot programming to be automated and completed in a few seconds. This technique is applicable to a wide range of industrial wear applications.
