Optimizing waveforms for positioning in 5G [PDF]
2016 IEEE 17th International Workshop on Signal Processing Advances in Wireless Communications (SPAWC), 2016 Today's mobile radio systems deploy reference signals which can be used or which are even dedicated for signal propagation delay-based mobile terminal positioning. Usually, the signal power of such reference signals is uniformly distributed over the available spectrum.
