Abstract

See full text

A method for carrier aggregation receives a signal with multiple non-contiguous carrier bands. Frequency converting of the signal to a compressed single intermediate frequency band with a pseudonoise code applied to a local oscillation of each of the multiple non-contiguous carrier bands while maintaining separation of the multiple non-contiguous carrier bands permits reduced complexity digital signal processing to detect spectral power density and demodulate waveforms across multiple channels. A receiver includes a pseudorandom noise generator applying a pseudo noise code to the local oscillator generator to produce a unique set of spectral tones in the output signal that sample-specific channels over the multiple non-contiguous carrier bands.
