Ultra-wideband frequency hopping spread spectrum (UWB-FHSS) solutions are used for transceiver architectures. These UWB-FHSS transceiver architectures can transmit and accurately digitize frequency hops over an extremely wide bandwidth while using a relatively slow analog-to-digital converter (ADC) without suffering from unacceptable performance degradation. For example, ADCs can be used having sample rates lower than standard Nyquist criteria would require for the bandwidth of the spread spectrum utilized.
