Latest Patents

One of her latest patents involves a method and arrangement for estimating transmitted symbols in a digital time-shared transmission system. In this innovation, a receiver processes a signal with a symbol rate lower than the channel bandwidth. The system includes a correlating and sampling circuit that samples the baseband signal multiple times per symbol time, performs channel correlation, and generates a channel estimate. This method enhances the performance of the channel equalizer, which utilizes a fractional Viterbi algorithm to generate estimated symbols. The use of weighting factors improves the metric calculation, simplifying the overall design of the channel estimating filter and equalizer.

Another significant patent focuses on frequency and channel hopping communication in a TDMA cellular mobile system. This invention allows base and mobile stations to transmit radio signal bursts in time slots across multiple radio channels while avoiding coincidence on any channel within the same cell. The system estimates signal characteristics such as signal strength and bit error rate, allowing for controlled output power of the stations. This innovation ensures efficient communication and minimizes interference among mobile stations.
