- Abstract
- The broadcast networks in reality may suffer from unexpected network failures, which attribute to the pilot signal overlap between the desired signal and the co-channel interference (CCI) from untrusted adjacent transmitters. This paper demonstrates the feasibility of a transmitter carrier offset (TCO) technique to resolve the pilot contamination problem in Advanced Television Systems Committee (ATSC) 3.0 systems. Based on professional exciters and commercial receivers that fully comply with ATSC 3.0 standards, laboratory experiments are conducted to verify the TCO gain in several service scenarios. The experiments specifically address a single CCI-source case, and the presented results show that the ATSC 3.0 TCO effectively alleviates the signal-to-interference ratio (SIR) requirement penalty due to the unfortunate signal overlapping.
