Abstract
The problem of receiving ultra-wideband (UWB) chaotic radio pulses of microwave band that passed through a multipath channel is considered. Based on measurements of UWB chaotic radio pulse propagation through a real wireless channel, a method for reception is proposed that is not affected by interpulse interference.
Highlights
A method for blind energy detection of ultra-wideband (UWB) chaotic radio pulses of microwave band that is not affected by interpulse interference due to multipath propagation of the UWB signal [1] is proposed
Noncoherent detection of chaotic radio pulses in a multipath channel is not a problem when the propagation delays of the reflected paths do not exceed the duration of the interpulse guard interval [2,3,4]
Problems with coherent and noncoherent detection of UWB signals appear for both chaotic UWB radio pulses [5, 6] and ultrashort UWB pulses [7], if the delays of the reflected path go beyond the limits of the interpulse guard interval, which is typical, e.g., for mobile wireless systems
Summary
A method for blind energy detection of ultra-wideband (UWB) chaotic radio pulses of microwave band that is not affected by interpulse interference due to multipath propagation of the UWB signal [1] is proposed. Noncoherent detection of chaotic radio pulses in a multipath channel is not a problem when the propagation delays of the reflected paths do not exceed the duration of the interpulse guard interval [2,3,4].
