Abstract:
1. An ultra-wideband communication method, the method comprising the steps of: transmitting a serial data stream comprising a plurality of ultra-wideband pulses; receiving the serial data stream; splitting the serial data stream into a plurality of parallel data streams; shifting a frequency of at least one of the plurality of parallel data streams; combining the plurality of parallel data streams into a combined data stream; and equalizing the combined data stream, wherein the step of equalizing employs an equalizer that comprises: a hard decision element configured to generate a hard decision estimate of an input sample; a past decision element configured to multiply at least one past decision estimate with an associated coefficient; a future decision element configured to multiply at least one future decision estimate with an associated coefficient; and further comprising a forward error correction element communicating with the equalizer, wherein the hard decision estimate is fed to the forward error correction element; wherein the future decision element is fed by the forward error correction element.
