A new WOFDM design for high data rates in the case of trains communications

Pushed by international trends to develop intelligent transport systems, railways operators rely more and more on the new information and communication technology to optimize exploitation and maintenance costs but also to enhance the friendliness, comfort and security feeling of public transport by offering new services to passengers while traveling. There is not a lot of study dealing with the problem of high data rate services both in uplink and downlink directions in the case of highspeed trains. This paper investigates a new wavelet based OFDM system that enables high data rate transmission and improve spectral efficiency significantly. The performances of this new technique is analyzed in terms of spectral efficiency
