Abstract
A method for processing a RF signal. The method includes receiving the signal having a sequence of chips, sampling the signal to generate a sampled signal, generating, based on the sequence of chips, a cancellation signal, subtracting the cancellation signal from the sampled signal to generate a cancelled signal, and performing an accumulation based on the cancelled signal to generate a channel impulse response (CIR) estimation.
Claims20
A method for processing a signal, comprising:
- receiving the signal comprising a sequence of chips;
- sampling, by an analog-to-digital converter (ADC), the signal to generate a sampled signal;
- generating, based on the sequence of chips, a cancellation signal;
- subtracting the cancellation signal from the sampled signal to generate a cancelled signal;
- and
- performing an accumulation based on the cancelled signal to generate a channel impulse response (CIR) estimation.
An ultra-wideband (UWB) device, comprising a UWB receiver comprising an analog-to-digital converter (ADC), wherein the receiver is configured to:
- receive, at the ADC, a signal comprising a sequence of chips;
- sample, by the ADC, the signal to generate a sampled signal;
- generate, based on the sequence of chips, a cancellation signal;
- subtract the cancellation signal from the sampled signal to generate a cancelled signal;
- and
- perform an accumulation based on the cancelled signal to generate a channel impulse response (CIR) estimation.
A non-transitory computer-readable medium (CRM) having program code recorded thereon, the program code comprising:
- code for causing an ultra-wideband (UWB) device to receive a signal comprising a sequence of chips;
- code for causing the UWB device to sample the signal to generate a sampled signal using an analog-to-digital converter (ADC);
- code for causing the UWB device to generate, based on the sequence of chips, a cancellation signal;
- code for causing the UWB device to subtract the cancellation signal from the sampled signal to generate a cancelled signal;
- and
- code for causing the UWB device to perform an accumulation based on the cancelled signal to generate a channel impulse response (CIR) estimation.
