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 1):
A transceiver, comprising:\n a first antenna to receive an input signal, wherein the input signal is an RF signal spanning a wide band of frequencies and including weak signals and a strong signal; a first analog to digital converter (ADC) coupled to receive the input signal and provide a digital sample signal in response, wherein the first ADC oversamples the input signal, wherein the digital sample signal at least includes a sample of the strong signal, and wherein the ADC is a N-bit ADC; a first digital signal processor coupled to receive the digital sample signal and provide a digital cancellation signal in response, wherein the digital cancellation signal is a complementary estimation of the digital sample, wherein the first digital signal processor generates the digital cancellation signal using M-bits, wherein M is greater than N; a first digital-to-analog converter (DAC) coupled to receive the digital cancellation signal and provide an analog cancellation signal in response; and an adder coupled to receive the input signal and the analog cancellation signal and provide a residual analog signal in response, wherein the residual analog signal is the combination of the input signal and the analog cancellation signal, and wherein the strong signal is at least reduced in the residual analog signal due to the analog cancellation signal.
