Abstract
Time reversal (TR) communications marks a paradigm shift in ultrawideband (UWB) communications. The system complexity can be shifted from the receiver to the transmitter, which is ideal to some applications. UWB multiple input-single output (MISO) is enabled by the use of the TR scheme. Two basic problems are investigated experimentally using short UWB radio pulses (nanosecond duration). Temporal focusing and increase in collected-energy with the number of antennas are verified. Also, the reciprocity of realistic channels, the cornerstone of TR, is demonstrated perhaps for the first time in electromagneticsKeywords
