| 20100183106 | SYSTEM AND METHOD FOR COMPENSATING FOR NONLINEAR INTERFERENCE CANCELLATION IN MULTI-CARRIER TRANSMISSION - An aspect of the present invention is drawn to a receiver operable to receive a first signal transmitted on a first carrier and to receive a second signal transmitted on a second carrier. The receiver includes a first filter, a second filter and a nonlinear compensator. The first filter is arranged to receive the first signal and to generate a first filtered signal. The second filter is arranged to receive the second signal and to generate a second filtered signal. The nonlinear compensator is arranged to output a first compensating signal based on the first filtered signal and the second filtered signal and to output a second compensating signal based on the first filtered signal and the second filtered signal. Further, the nonlinear compensator can reduce one of nonlinear interference within the first filtered signal and nonlinear interference between the first filtered signal and the second filtered signal. | 07-22-2010 |
| 20110103507 | SYSTEM AND METHOD FOR COMBINED PREDISTORTION AND INTERFERENCE CANCELLATION IN A SATELLITE COMMUNICATIONS SYSTEM - The present invention provides a communication system for use with a first source signal and a second source signal. The first source signal is on a first channel and includes M symbols, where M is an integer greater than 1. The second source signal is on a second channel and includes X symbols, where X is an integer greater than 1. The first channel is different from the second channel. The communication system includes a first modulator unit, a second modulator unit and an adder. The first modulator unit can generate a first modulated signal based on the first source signal and includes a first inter-symbol distortion estimating unit and a first stage predistortion unit. The second modulator unit can generate a second modulated signal based on the second source signal and includes a second inter-symbol distortion estimating unit and a predistortion unit. The adder can generate an added signal based on the first modulated signal and the second modulated signal. The first inter-symbol distortion estimating unit can generate a distorted symbol vector based on an estimate of a distortion of the first through (a−1)-th symbols and an estimate of a distortion of the (a+1)-th through M-th symbols, where 1≦a≦M. The first stage predistortion unit is operable to generate a predistorted symbol ã based on the symbol a of the first plurality of symbols and the distorted symbol vector. Further, a receiver unit can cancel interference in the received signals to account for adjacent channel interference. | 05-05-2011 |

| 20100278301 | STEREOSCOPIC X-RAY SYSTEM AND METHOD - Disclosed are systems and methods for obtaining stereoscopic x-ray images. The method includes taking two digital x-ray views of the same object from differing positions. The included angle between the axes of the x-rays for each position generally coincides with that formed by a pair of eyes viewing the object, though larger angles can be used. The x-rays can be taken by two x-ray generators within a single housing or within separate but attached housings. The generators are spaced apart and aimed at the object to form the appropriate angle. Care is taken not to move the object. Preferably, the x-ray generators have dual collimators to take the views. In this case, the time between taking the two x-rays need only be as long as the image capture time of the sensor being used, which lessens the chance of the object moving. | 11-04-2010 |

| 20080235088 | System for measuring web traffic related to an offline advertising campaign - A system is described for measuring web traffic relating to an offline advertising campaign. The system may include a processor and a memory. The memory may be operatively connected to the processor and may store an offline advertising campaign of an advertiser, a time period, a set of users and web traffic data. The processor may identify the offline advertising campaign, and the period of time the offline advertising campaign was available to a set of users. The processor may measure the web traffic related to the offline advertising campaign of the users during the time period. | 09-25-2008 |
| 20080235089 | SYSTEM FOR SERVING ADVERTISEMENTS BASED ON OFFLINE ADVERTISING CAMPAIGNS - A system is described for serving an online advertisement based on an offline advertising campaign. The system may include a memory, an interface and a processor. The memory may be operatively connected to the interface and the processor and may store an offline advertising campaign of an advertiser, an advertising effect period, a set of users, and an online advertisement. The interface may be operatively connected to the memory and may be used to serve the online advertisement to the users in the set of users. The processor may be operatively connected to the memory and the interface. The processor may identify the offline advertising campaign and the advertising effect period, the period when the offline advertising campaign is capable of effecting the online behavior of the set of users. The processor may identify an online advertisement relating to the offline advertising campaign. The processor may serve the online advertisement, to the users in the set of users, via the interface, during the advertising effect period. | 09-25-2008 |
