Joint use of 5G waveform UFMC and Non Uniform Constellations in DVB-T2

Abstract:

The Digital Video Broadcasting-Terrestrial, second generation (DVB-T2) system has been the object of many research during the last decade and is now mature. This paper focuses on the identification of the maximum obtainable performance improvement of DVB-T2 CP-OFDM with NUCs in typical TU6 fading environment. It first concentrates on the ultimate improvement achievable using joint UFMC and NUCs in standardized DVB-T2 system. In these conditions, a 0.5 dB SNR improvement (for BER=3.10-3) is reported in TU6 using CP-OFDM NUC 32K 256-QAM and CR=1/2 and 3/5 in place of sole CP-OFDM. Also, using in conjunction both studied technologies, namely UFMC NUC 32K 256-QAM CR=1/2 and 3/5, an SNR improvement of 1.2 dB (for BER=3.10-3) is achievable which provides a good SNR margin e.g. to increase the emitter's coverage.
