SDR implementation of a DVB-T2 transmitter: The core building blocks

Abstract

In this paper we describe the implementation of a DVB-T2 transmitter on a commercially-available hardware platform. The implementation leverages on the Software-Defined Radio (SDR) characteristics of the platform to attain on-the fly reconfigurability. The paper focuses on the two most computationally intensive blocks of the transmitter: the LDPC encoder and the IFFT processor.
