Ultra-Wideband Communication System for Very High Data Rates
First Claim
1. An ultra-wideband information transmission method comprisinga first encoding step on the part of the transmitter, in which a pulse group which is formed from a predetermined number of individual pulses in such a way that the individual pulses partially overlap in respect of time after the pulse forming operation is encoded in dependence on values of a random number sequence, anda correlation step on the part of the transmitter in which correlation of a reception signal with a signal pattern is effected,characterized in that the signal pattern corresponds to the whole pulse group to be expected when using the same values of the random number sequence.

Abstract
The invention concerns an ultra-wideband information transmission method comprising a first encoding step on the part of the transmitter, in which a pulse group which is formed from a predetermined number of individual pulses is encoded in dependence on values of a random number sequence, and a correlation step on the part of the receiver in which correlation of a reception signal with a signal pattern is effected, wherein the signal pattern corresponds to the whole pulse group to be expected when using the same values of the random number sequence.

17. An ultra-wideband transmitting apparatus having a pulse group generator comprising
a pulse generator which is adapted to deliver individual pulses at a predeterminable time spacing from each other, a code generator which is adapted to deliver random signals dependent on the values of a random number sequence, an encoding unit which is adapted to encode an individual pulse delivered or to be delivered by the pulse generator in dependence on the current random signal, and a control unit which is connected to the pulse generator and which is adapted to actuate the pulse generator at predeterminable moments in time for the delivery of a pulse group with a predetermined number of encoded individual pulses at predetermined time spacings from each other.

23. An ultra-wideband receiving apparatus having a pulse group generator comprising
a pulse generator which is adapted to deliver individual pulses at a predeterminable time spacing from each other, a code generator which is adapted to deliver random signals dependent on the values of a random number sequence, a first encoding unit which is adapted to encode an individual pulse delivered or to be delivered by the pulse generator in dependence on the current random signal, and a control unit which is connected to the pulse generator and which is adapted to actuate the pulse generator at predeterminable moments in time for the delivery of at least one signal pattern in the form of a pulse group with a predetermined number of encoded individual pulses at predetermined time spacings from each other, and with a correlation unit which is connected to the pulse group generator and adapted to deliver an output signal dependent on the correlation of a reception signal with the signal pattern.
