20090111398 | Transmitter and transmission method - There is provided an apparatus, having a first local oscillator generate a first oscillation signal, a first mixer generating a transmit signal by mixing an input signal and the first oscillation signal, an observation receiver receiving a portion of the transmit signal, and applying, in a first operation mode of the apparatus, the received portion of the transmit signal such that a transmit signal component on a frequency of the first oscillation signal falls into a band-pass frequency of the observation receiver, and shift, in a second operation mode of the apparatus, the received portion of the transmit signal such that an oscillation leakage signal component of the first oscillation signal falls into the band-pass frequency of the observation receiver; and a compensation unit generating a compensation signal based on the band-pass signal of the observation receiver for compensation of the input signal. | 04-30-2009 |
20100093282 | MULTI-TRANSCEIVER ARCHITECTURE FOR ADVANCED Tx ANTENNA MONITORING AND CALIBRATION IN MIMO AND SMART ANTENNA COMMUNICATION SYSTEMS - Exemplary embodiments of system and method are provided for measuring signal amplitude, phase and/or delay offsets between multiple transmit signals fed through the transmit signal processing chains and wirelessly transmitted over the transceive antennas of separate transceiver modules, wherein transmit signal coupling between the transmit antennas of said transceiver modules' transmit signal processing chains may be used for synchronizing the transmit signals and calibrating their amplitude, phase and/or delay parameters. The exemplary embodiments further provide a front end arrangement of a wireless transceiver device which can comprise at least two independently controllable transceiver modules, each connected to an associated spatial diversity transceive antenna and comprising at least one associated transmit signal processing chain and at least one associated receive signal processing chain coupled to a common baseband processing unit. The exemplary transceiver architecture can be executed on an antenna loop between the transmit signal processing chain of a first transceiver module and the transmit signal processing chain of a second transceiver over the air interface and relies on an adaptive antenna concept which facilitates a wireless transmission of data via a plurality of wireless communication channels utilizing an array of transceive antennas, receiving feedback information via at least one of said communication channels using such antenna loop and modifying a transmission mode based on the received feedback information. | 04-15-2010 |

20090215200 | Measurement of binding rate of a binding substance and an analyte - A method of measuring the rate of binding of a binding substance and an analyte, for example in an assay such as an immunoassay, uses an initial step of performing ultrasonication sufficient to disrupt binding between the binding substance and the analyte. After cessation of the ultrasonication, measurements are taken to determine the rate of binding at cessation of said ultrasonication or at a predetermined time thereafter The ultrasonication results in knowledge of the precise time of the start of the binding reaction which provides a better rate measurement. | 08-27-2009 |
