Latest Patents
One of her latest patents is a "Method and apparatus for monitoring a redundant (standby) transmitter in a radio communications system." This invention involves a method for monitoring a redundant transmitter, which is part of a base station in a point-to-multipoint radio communications system. During normal operation, a spread-spectrum signal is transmitted over the redundant transmitter, which has low spectral power compared to the data signals from the active transmitter. Receivers associated with terminal stations detect the presence of this spread-spectrum signal. If the signal is absent, the receivers indicate this, allowing for a decision regarding the integrity of the redundant transmitter.
Another significant patent is the "Method for linearizing high-frequency amplifier." In this invention, a predistorter is connected upstream of a high-frequency amplifier to be linearized. The predistortion factor is adaptively modified to compensate for the amplifier's non-linearities. The output signal of the high-frequency amplifier and the input signal of the predistorter are analyzed to determine an average amplification. A correction term is produced for the predistortion factor, which is adjusted to minimize the correction term.
