This paper presents an implementation of the IEEE 802.15.3c standard, in Simulink, for high data-rate applications. The recent standard IEEE 802.15.3c provides the implementation of such wireless communication system using the 60GHz frequency band. OFDM and SC-FDE are the two transmission schemes adopted by the standard. Performance of these technologies at mm-wave signals are severely affected by nonlinearity of the RF front-ends. This paper presents the impact of RF impairments for each transmission scheme along with comparative analysis, in terms of BER and PSNR.
