A Generalized Maximum Distance Separable Coded Framework Design for Vehicular RadCom

For achieving joint radar and communication (RadCom) as well as improving communication quality in vehicular networks, this paper designs a generalized maximum distance separable (MDS) coded framework, which is suitable for the conventional communication waves, such as orthogonal frequency division multiplexing (OFDM), also for the radar sensing waves, such as frequency modulated continuous wave (FMCW). In the framework, an MDS coded amplitude and phase modulation (MDS-APM) scheme is utilized in order to correct the burst error in channels and hence achieve reliable communication, while the efficient two-dimensional fast fourier transform (2D-FFT) algorithm is employed for multi-target sensing. To exploit the potential benefits of different waveforms, we further compare the MDS-based OFDM design and MDS-based FMWC design. Numerical simulations are conducted to evaluate their performances, which prove that both waveforms have attractive radar performances, while their communication qualities differ in distinct scenarios.
