DATA TRANSMITTER AND DATA RECEIVER
First Claim
1. A data transmitter for transmitting a data packet to a data receiver via a communication channel, comprising:
- a generator for generating the data packet comprising a first data block and a second data block and a predefined first reference sequence and second reference sequence for synchronizing the data packet in the data receiver, wherein the first reference sequence is longer than the second reference sequence, and wherein in the data packet, the second data block is located between the first reference sequence and the second reference sequence, and the first reference sequence is located between the first data block and the second data block; and
a transmitter for transmitting the data packet to the data receiver via the communication channel;
wherein the generator for generating the data packet is configured to provide, in the data packet, the first reference sequence to be double the length of the second reference sequence; and
wherein the generator for generating the data packet is configured to subdivide, in the data packet, the first reference sequence into a first reference subsequence and a second reference subsequence, the first reference subsequence and the second reference subsequence each comprising the length of the second reference sequence.

Abstract
A data transmitter for transmitting a data packet to a data receiver via a communication channel includes a generator for generating the data packet and a transmitter for transmitting the data packet. The generator for generating the data packet is configured to generate a data packet having a first data block and a second data block and a predefined first reference sequence and second reference sequence for synchronizing the data receiver, wherein the first reference sequence is longer than the second reference sequence, and wherein in the data packet, the second data block is located between the first reference sequence and the second reference sequence, and the first reference sequence is located between the first data block and the second data block. The transmitter for transmitting the data packet is configured to transmit the data packet to the data receiver via the communication channel.
