Abstract
A method and device are described for determining an error rate during transmission from a transmitter/receiver station to a transmitter/receiver device and a measuring device. A first data block and at least one other and different redundant block is received by the transmitter/receiver device, decoded, and checked for transmission errors. If an error is ascertained in the first data block, another redundant block is requested, but in response the first data block is retransmitted instead.
Claims12
A method for determining an error rate in a data transmission from a transmitter/receiver station to a transmitter/receiver device, wherein a first data block and at least one further, redundant data block different from the latter are generated by the transmitter/receiver station from an original data block and, in the event of an error transmission of the first data block, a further, redundant data block is requested by the transmitter/receiver device, comprising the steps of:
- transmitting a first data block by the transmitter/receiver station,
- receiving the first data block by the transmitter/receiver device,
- decoding the first data block received in a decoding block,
- checking the first data block for transmission errors,
- requesting a further, redundant data block for error correction, if an error is determined in the transmitted data of the first data block,
- receiving the request in the transmitter/receiver station,
- retransmission the first data block instead of a redundant data block, and
- determining the rate of the incorrectly received first data blocks.
A measuring device for determining an error rate in the event of a data transmission from a transmitter/receiver station to a transmitter/receiver device, comprising:
- a coding block for generating from an original data block a first data block and at least one further, redundant data block different from latter, and
- a selection device for selecting a data block to be transmitted, wherein the first data block is retransmitted by the transmitter/receiver station instead of a redundant data block in response to a request for a further, redundant data block communicated by the transmitter/receiver device to the transmitter/receiver station because of a error transmission of the first data block.
