Concept for combining coded data packets

摘要

Concept for transmitting payload data from a transmitter to a receiver via a communication channel within a time interval, wherein channel-coded data packets are generated from the payload data, wherein each of the channel-coded data packets has packet core data corresponding to a packet identification of the respective channel-coded data packet, and wherein the packet core data is coded with a channel code of higher redundancy than the payload data. The channel-coded data packets are sent without any return channel to the receiver, which decodes packet core data of a first received channel-coded data packet of the time interval. If error-free decoding of the first channel-coded data packet fails, packet core data of at least one second received channel-coded data packet of the time interval are decoded to determine a suitable further channel-coded data packet for combination with the first channel-coded data packet to acquire, on account of the combination, an increased code gain for decoding of the payload data.

1. A transmitter apparatus configured to transmit payload data via a unidirectional communication to a receiver apparatus within a time interval, comprising:
a generator configured to generate a plurality of channel-coded data packets from the same payload data, each of the channel-coded data packets comprising packet core data corresponding to a packet identification which is different for each data packet, and the packet core data being coded with a channel code of a higher redundancy than the payload data; and a transmitter configured to transmit the plurality of channel-coded data packets to the receiver apparatus within the time interval, the transmitter being configured to transmit the plurality of channel-coded data packets from the transmitter apparatus to the receiver apparatus within the time interval without using a return channel; wherein if a transmission of the channel-coded data packets is sufficiently error-free, the channel-coded data packets are individually decodable, by themselves, to provide the payload data; and if a transmission of the channel-coded data packets is not sufficiently error-free, at least two of the channel-coded data packets are combinable to provide, according to the combination of the at least two of the channel-coded data packets, an increased code gain to decode the channel-coded data packets to provide the payload data.
