Latest Patents

One of Jard's latest patents is related to transmission power management. This invention outlines a method for adjusting transmission power on a downlink radio channel within a communication system that includes user equipment and a base station. The method involves determining uplink power headroom by dividing the maximum transmission power of the user equipment by the transmission power of a control channel. The calculated uplink power headroom value is then sent to the base station. Following this, an uplink path loss estimate is determined, which is used to derive an estimate for the downlink path loss. Ultimately, the transmission power of the downlink radio channel is adjusted based on this estimate.

Another significant patent by Jard is a spread spectrum modulator and demodulator. This invention converts input sequences composed of digital symbols into spread-spectrum sequences. The modulator generates a spreading code and combines it with the input sequences to produce multiple spread spectrum sequences for transmission from various antennas of a radio transmitter. Each sequence corresponds to a sum of at least two contributions that are time-shifted, ensuring efficient transmission.
