Effect of multipath amplification is found in ultrawideband wireless communication systems with chaotic carrier, whereas information is transmitted with chaotic radio pulses. This effect is observed in multipath environment (residence, office, indust
rial or other indoor space). It exhibits itself through an increase of signal power at the receiver input with respect to the case of free space. Multipath amplification effect gives 5-15 dB energy gain (depending on the environment), which allows to have 2-6 times longer distance range for the same transmitter power.
