This paper evaluates the theoretical performance of signal tracking in a noisy single-path environment using 5G-microwave and LTE signals. Such OFDM signals suit navigation applications thanks to build-in symbol sequences which despite being designed for communication services since are known at the receiver can be exploited for pseudorange computation. By using multiple numerologies, 5G is putting into place an important degree of flexibility which was not explored before. It turns out, the numerology counts towards the signal tracking performance. However, the nominal tracking capacity expressed by 5G-microwave signals at the highest sampling frequency is reduced due to the lack of full bandwidth useful signals. Top-ranked LTE-CRS performance can hypothetically improve by aggregating multiple carrier components.
