Uncompressed Full HD Video Transmission using Uncoded OFDM over Multipath Fading Channels at 60 GHz

摘要

This paper presents a detailed analysis of the impact of channel impairments on the performance of a mm-Wave wireless uncoded Orthogonal Frequency Division Multiplexing (OFDM) architecture system based on IEEE 802.15.3c standard, for high data-rate applications. The performance of OFDM is known to be severely affected by multipath fading channel when its excess delay exceeds the time guard interval of the OFDM symbol. Hence, this paper analyses the impact of uncompressed Full HD video content transmission over various radio propagation environments suggested by the standard. The impact of the propagation channel impairments is evaluated through appropriate metrics based on Bit Error Rate (BER) and Peak Signal-to-Noise Ratio (PSNR) analysis for residential, office and kiosk scenarios under Line-Of-Sight (LOS) and Non-Line-Of-Sight (NLOS). The feasibility of real-time high-definition video transmission using 60 GHz radio systems will be demonstrated through a proof-of-concept test, which will allow one to perfectly understand the system limitations, and consequently the range of applications that might be developed.
