Publikováno v: EURASIP Journal on Wireless Communications and Networking, Vol 2010 (2010)

A new modulation scheme is proposed for a time reversal (TR) ultra wide-band (UWB) communication system. The new modulation scheme uses the binary pulse amplitude modulation (BPAM) and adds a new level of modulation to increase the data rate of a TR
