Patent ID: 8760334

Claim:
Apparatus for use in an ultra-wideband (UWB) communication system in which multi-symbol packets are transmitted via a transmission channel, each transmitted packet comprising a multi-symbol data payload, the apparatus comprising: an analog-to-digital converter (ADC) adapted to: receive a conditioned form of a received packet; periodically sample said packet at a selected over-sample rate; and provide corresponding samples, each sample comprising a selected one of: a sign bit having a first value indicative of said sample being positive, and a second value indicative of said sample being negative; or a single trit having a first value indicative of said sample being positive, a second value indicative of said sample being substantially zero, and a third value indicative of said sample being negative; or a sign bit and a magnitude bit: said sign bit having a first value indicative of said sample being positive, and a second value indicative of said sample being negative; and said magnitude bit having a first value indicative of said sample being substantially zero, and a second value indicative of said sample being substantially non-zero; and a digital channel matched filter adapted to receive a selected set of the samples, and to develop therefrom a multi-value result vector as a function of a best estimate of a channel impulse response (CIR) of said channel, the CIR estimate comprising a set of coefficients.
