1. A method for receiving and processing a radio signal in a transmitter-receiver environment, comprising:
- receiving the radio signal having at least two pulses and a fixed time between the at least two pulses;
amplifying the received radio signal;
generating a larger-amplitude signal with an amplitude greater than an amplitude of the received radio signal;
amplifying the larger-amplitude signal;
replicating the larger-amplitude signal to generate at least two duplicate signals;
generating a timing sequence;
replicating the timing sequence into a plurality of timing sequences each delayed in time; and
outputting at least a first counter value responsive to a value of one of the plurality of timing sequences being valid when the value of at least one of the at least two duplicate signals transitions.

Abstract
Provided are a method and apparatus (receiver) of receiving and processing a radio signal in a transmitter-receiver environment. The radio signals are transmitted across a wireless interface using Ultra Wideband (UWB) pulses. A transmitted reference approach is utilized. The radio signal include pairs of UWB pulses with each pair of pulses separated by a fixed time delay. The two pulses are then combined to provide for improved noise immunity.

11. A receiver, comprising:
-
a receiving stage that receives a radio signal having at least two pulses and a fixed time between the at least two pulses; an amplifier stage that amplifies the received radio signal; a signal modification stage that generates a signal having an amplitude larger than an amplitude of the received radio signal; an amplification stage that amplifies the larger-amplitude signal; a fan-out stage that replicates the larger-amplitude signal and generates at least two duplicate signals based at least in part on the replicated larger-amplitude signal; a sequence generator stage that serially generates a timing sequence; at least one sequence delay stage that replicates the timing sequence into a plurality of timing sequences each delayed in time; and at least one counter control stage that outputs a counter value responsive to a pulse of one of the duplicate larger-amplitude signals and one of the plurality of timing sequences. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
