20090103568 | Method and System for Non-Gaussian Code-Division-Multiple-Access Signal Transmission and Reception - The present invention relates to a method and system for non-Gaussian code-division-multiple-access signal transmission and reception. Input probability data indicative of a non-equiprobable channel input probability mass function are determined based on received channel data indicative of characteristics of a CDMA transmission channel. The input probability data are determined such that a transmission signal received after transmission has a non-Gaussian distribution. Upon receipt of input user data, a CDMA signal is generated by modulating the received user input data in dependence upon the input probability data and provided for transmission. After transmission a received transmission signal is first processed for determining second channel data and then for determining an estimate indicative of the user input data based on the second channel data. | 04-23-2009 |

20100176952 | SYSTEM FOR DETECTION OF BODY MOTION - An approach for determining motions of a body using distributed sensors is disclosed. In one embodiment, an apparatus can include: a plurality of sensors coupled to a body, where each sensor is positioned at about a designated location on the body, and where each sensor is configured to acquire motion data related to movement of the designated location on the body and at which the sensor is positioned, and to reduce the motion data into compressed and transmittable motion data; and a base station configured to receive the compressed motion data via wireless communication from at least one of the plurality of sensors, the base station being further configured to remove outlier information from the received motion data, and to match the received motion data to a predetermined action, where the predetermined action indicates a movement of the body. | 07-15-2010 |
