Abstract :
The globally available large unlicensed frequency spectrum around 60GHz has recently gained a lot of attention. Its broad bandwidth, combined with a high allowed transmitted power level, provides an excellent opportunity for numerous applications, among others high-precision ranging and localization. Despite being readily available at 60GHz, high bandwidths come with a significant power penalty in the baseband. The presented work brings a solution that delivers high ranging precision at heavily reduced processing bandwidths and sparse-bandwidth power allocations.
