Embodiment Construction

[0085] 1. Radio transmission system based on telegraph splitting

[0086] 1.1 Overview

[0087] figure 1 A schematic block diagram of a system with a data transmitter 100 and a data receiver 110 is shown. Data transmitter 100 may be configured to transmit signal 120 , wherein signal 120 includes at least two separate partial data packets 142 . The data receiver 110 may be configured to receive the signal 120 (or a version of the signal 120 modified by the transmission channel) comprising at least two separate partial data packets 142 .

[0088] From figure 1 As can be seen in , at least two separate partial data packets 142 are separated or spaced apart from each other in time and / or frequency. The time and / or frequency distribution of the at least two separate partial data packets 142 can take place according to the hopping pattern 140 .

[0089] In an embodiment, the data transmitter 100 may include a transmitting device (or transmitting module or transmitter) 102 confi...

Abstract

Embodiments represent a data receiver, wherein the data receiver is designed to receive a signal having a plurality of sub-data-packets, wherein the plurality of sub-data-packets (142) each have a portion of a data packet, wherein the data receiver has a multi-stage correlator which is designed to carry out a multi-stage correlation in order to detect the sub-data-packets in the received signal, wherein a second correlation stage of the multi-stage correlator functions of the basis of correlation results of a first correlation stage of the multi-stage correlator.

Description

technical field [0001] Embodiments relate to a data receiver, and in particular to a data receiver for receiving a wideband signal comprising a number of partial data packets distributed in time and frequency according to a time-frequency hopping pattern. Some embodiments relate to packet correlators for radio transmission systems. Background technique [0002] A radio transmission system based on telegram splitting is known from DE 10 2011 082 098 B4, wherein a data packet (or telegram) to be sent is divided into a plurality of partial data packets, wherein each of the plurality of partial data packets A partial data packet is shorter than said data packet, and wherein a plurality of partial data packets are sent distributed in time and frequency according to a time-frequency hopping pattern. [0003] When a plurality of data packets divided into partial data packets are transmitted simultaneously or in a time-overlapping manner by a plurality of data transmitters, the com...
