This paper presents a detailed analysis of the impact of multipath propagation phenomena on the
performance of mm Wave wireless systems for both uncoded and coded OFDM architectures, based on IEEE
802.15.3c standard for high data rate applications. The performance of OFDM is known to be severely affected
by channel impairments when its excess time delay exceeds the time guard interval of the OFDM symbol. Hence,
this paper evaluates the impact that such impairments have on both uncoded and coded system performances
through appropriate metrics based on BER, operating range and PSNR for residential, office and kiosk scenarios
under LOS and NLOS. The feasibility of real-time high-definition video transmission using 60 GHz radio systems
will be demonstrated through the transmission of uncompressed Full HD video content over various radio
propagation environments, which will allow one to perfectly understand the system limitations, and consequently
the range of applications that might be developed.
