Abstract:
Systems and methods for direct sample, extremely wideband transceivers are disclosed. An example transceiver includes an antenna, an N bit analog to digital converter a digital signal processor, a digital to analog converter, and an adder. The N bit ADC receives a wideband RF input signal from the antenna, where the input signal includes weak signals and a strong signal, oversamples the input signal and provides a digital sample signal. The digital signal processor generates a digital cancelation signal from the digital sample signal, where the digital cancellation signal is generated using M bits, M greater than N. The DAC provides an analog cancellation signal based on the digital cancellation signal, and the adder provides a residual analog signal from the addition of the input signal and the analog cancellation signal, where the strong signal is at least reduced in the residual analog signal due to the analog cancellation signal.

Claim (Index 11):
A method, comprising:\n sampling, by a first analog-to-digital converter (ADC), an input signal to provide a digital sample signal of at least the strong signal, wherein the first ADC is an N-bit ADC, and wherein the input signal is an RF input signal spanning a wide band of frequencies and includes weak signals and a strong signal; generating, by a first digital processor, a digital cancellation signal of the strong signal based on the digital sample signal, wherein the digital cancellation signal is an M-bit signal, M being greater than N; generating, by a first digital to analog converter (DAC), an analog cancellation signal based on the digital cancellation signal, wherein the analog cancellation signal provides a more precise estimate of the strong signal than the digital sample signal provides, and wherein the analog cancellation signal is a complement of the strong signal; and summing the analog cancellation signal and the input signal to provide a residual signal, wherein the residual signal includes the weak signals and a suppressed strong signal, and wherein the residual signal is an analog signal.
