Resumo
© 2021 IEEE.The study of new digital transmission technologies has increasingly gained importance. The implementation of digital radio has not yet been widely accepted, due to several cost factors and regional limitations. This article proposes the study of Digital Radio Mondiale Plus (\mathbf{DRM +}) in the Very High Frequency (VHF) band with Low-Density Parity-Check (LDPC) channel codes and Layered Division Multiplexing (LDM) technique. The development of \mathbf{DRM +} was carried out using Software Defined Radio (SDR), which guarantees lower production costs and the ability to develop new packages without having to change the hardware. The results obtained demonstrate that the \text{DRM} + combined with LDPC and LDM techniques guaranteed the system a gain, when compared to the standard system it had a reduction of 1.5 dB in Signal Noise Ration with a Quadrature Phase-Shift Keying (QPSK).
