Title: Martin Allander and Passive Intermodulation Avoidance

Introduction

Martin Allander is an inventor associated with Telefonaktiebolaget LM Ericsson (publ) in Stockholm, Sweden. His patent work addresses passive intermodulation (PIM), a radio-frequency interference issue that can affect wireless communications.

Latest Patents

The supplied information identifies one patent for Allander: “Techniques for Passive Intermodulation Avoidance.” The invention describes a controller-based method for reducing uplink PIM during signal transmission. The controller determines which fraction of transmission resources in a slot should receive a transmission-power reduction factor. It makes this determination in the logarithmic domain through a feedback control loop, comparing the measured PIM improvement from the most recent slot with a reference value. The measurement is obtained by probing the radio channel in each slot. The controller then applies the power reduction factor to the selected fraction of resources.

Career Highlights

Allander’s listed patent reflects work on adaptive control techniques for managing interference in radio systems. The method uses measured channel behavior and feedback to adjust transmission power across selected resources, rather than applying the reduction uniformly.

Collaborations

The patent information lists Torbjörn Wigren as Allander’s coworker. Allander is associated with Telefonaktiebolaget LM Ericsson (publ), a telecommunications company.

Conclusion

Martin Allander’s identified invention applies feedback-based power control to help avoid uplink passive intermodulation, contributing a targeted approach to interference management in wireless communications. His listed portfolio includes 1 patent.
