Combined Time and Space Diversity: Mobile Reception in DVB-T and DVB-T2 Systems

摘要

The simultaneous delivery of fixed and mobile services in digital terrestrial TV (DTT) networks is a very attractive concept, as it allows the reuse of content, spectrum, and infrastructure. However, the provision of mobile services in terrestrial networks is challenged by the more severe propagation conditions of the mobile scenario. In this context, significant gains can be achieved by exploiting the diversity over time, frequency, and space.
