This article presents enhancements that further improve the performance of 5G New Radio time division duplex (TDD) operation and performance. The focus is on mechanisms to mitigate co-channel cross link interference (CLI) between neighboring cells, p

Dynamic Point Blanking (DPB) is a Coordinated MultiPoint (CoMP) technology that has attracted significant interest for inter-cell interference mitigation in wireless communication systems due to its potential performance gain, robustness and relative

We describe a hybrid evanescent-wave sensor component that we fabricated by using an integrated optical interferometer with a specially adapted photodetector array. The design of the interferometer is based on the use of tapered waveguides to obtain

A flat-response multi-peak sampled fibre Bragg grating has been realised using a novel fabrication technique and has been used in a widely tunable hybrid semiconductor laser. The laser shows 45 nm tunability in C-band and sidemode rejection better th
