ABSTRACT:
Methods and apparatus for transmitting, receiving, and processing wideband signals with reduced discrete power spectral density components are disclosed. The wideband signals with reduced discrete power spectral density components are generated through pulse modulation, repeating and time hopping, and random inversion. A receiver reverses the random inversion and demodulates the signal.
