| 20090203339 | METHODS AND APPARATUS FOR PREDICTING A CHANNEL QUALITY INDICATOR IN A COMMUNICATION SYSTEM - Disclosed are methods and apparatus for predicting a channel quality indicator in a communication system, and in particular a delayed receiver. A disclosed method for determining the predictive channel quality indicator for a delayed receiver includes determining at least one channel quality indicator from a non-delayed receiver. The method also includes determining another channel quality indicator from the delayed receiver, and then calculating the predictive channel quality indicator for the delayed receiver through a function of the channel quality indicators from the non-delayed receiver and the channel quality indicator from the delayed receiver. Corresponding apparatus are also disclosed. | 08-13-2009 |
| 20090305654 | SYSTEM AND METHODS FOR DETERMINING RADIATED RADIO FREQUENCY (RF) RECEIVER SENSITIVITY - A test method is for determining RF sensitivity of an RF receiver for a plurality of channels extending over a frequency band(s) using an RF source coupled to the RF receiver by an RF communications link. The plurality of channels may include channels having a predictable RF sensitivity and a channel(s) having a non-predictable RF sensitivity. The test method may include measuring an RF sensitivity for one or more of the channels having the predictable RF sensitivity, and generating a partial RF sensitivity function for the channels having the predictable RF sensitivity based thereon. The method may further include measuring an RF sensitivity for the channel(s) having the non-predictable RF sensitivity. Additionally, an overall RF sensitivity function may be generated for the plurality of channels based upon the partial RF sensitivity function, and based upon the measured RF sensitivity for the channel(s) having the non-predictable RF sensitivity. | 12-10-2009 |

| 20130040593 | METHOD TO DETERMINE RF CIRCUIT ANTENNA IMPEDANCE - A process of estimating an admittance of an RF component using a ladder network with alternating series and parallel components by making three VSWR measurements and computing three admittance circle solutions in the complex admittance plane. The admittances circles are transformed through reference planes of the ladder network to obtain three RF component admittance circles, then estimating the RF component admittance using three nearest intersections of the three RF component admittance circles. Reference planes are defined immediately upstream and immediately downstream of each component of the ladder network. The transforms are performed using lumped parameter models of the series and parallel components of the ladder network. | 02-14-2013 |
