Resumo(s)
In this paper we introduce a dual-mode OFDM/SC-FDE 60 GHz millimeter wave (mmWave) Physical (PHY) layer to provide both radar and transmission data rates over 10 Gbps, as known as radar type sensors and wireless communications (Rad-Com). Such feature goes towards one of the vertical requirements for future wireless communications, such as 5G. The system is evaluated and assessed through metrics of BER and required Eb/N0 for a target BER of 10-5, under both residential LOS and NLOS scenarios. In the simulation results, it is demonstrated that SC-FDE is more robust against RF impairments, and does not requires channel coding contrary to OFDM. In addition to this, the fact that it has lower peak-to-average power ratio (PAPR), makes such transmission scheme a very promising alternative to OFDM. For example, employing 256 QAM modulation, it has 6 dB of Eb/N0 gain in comparison with OFDM, under the same conditions.
