Abstract
A method of transmitting data includes generating interleaved data. The method also includes converting the interleaved data into a modulated signal, and transmitting the modulated signal. The interleaved data is also stored, for example, in a buffer. The method further includes determining whether a retransmission of the modulated signal is required, and retransmitting the interleaved data based on a result of that determination.
Claims45
A method of transmitting data, comprising:
- interleaving data to generate interleaved data,
- converting said interleaved data into a modulated signal,
- transmitting said modulated signal,
- storing said interleaved data,
- determining whether a retransmission of said modulated signal is required, and
- retransmitting said interleaved data based on a result of said determining.
3 more elements
A transmitter, comprising
- an interleaver to provide interleaved data,
- a modulator operably coupled to said interleaver to convert said interleaved data into a modulated signal,
- a buffer unit operably coupled to said interleaver to buffer said interleaved data and operably coupled to said modulator to provide said buffered interleaved data thereto, and
- a retransmission controller, said retransmission controller including an input to receive an indicator indicating whether said interleaved data is to be retransmitted and an output operably coupled to said buffer unit to control outputting of said buffered interleaved data from said buffer unit to said modulator in dependence on said indicator.
1 more element
An arrangement for use in a receiver, comprising:
- a demodulator configured to generate a demodulated signal from a received orthogonal frequency division multiplexing symbol,
- a monitoring unit operably coupled to said demodulator to monitor corruption of said symbol based on trellis decoding information or digital-to-analog conversion saturation, and
- a retransmission request generator coupled to said monitoring unit to generate a retransmission request based on said monitored corruption.
A data transmission system, comprising:
- a transmitter comprising an interleaver to provide interleaved data, a storage unit coupled to said interleaver to store said interleaved data, an interface coupled to said storage unit to transmit a symbol generated based on said stored interleaved data, and a retransmission controller coupled to said storage unit,
- a receiver comprising an interface to receive said symbol, a monitoring unit coupled to said interface to monitor corruption of said symbol, and a retransmission request generator coupled to said monitoring unit,
- wherein said retransmission request generator is configured to generate a retransmission request if said monitored corruption exceeds a pre-determined threshold, and
- wherein said retransmission controller is configured to receive said retransmission request and to initiate outputting of said stored interleaved data from said storage unit to retransmit said interleaved data.
1 more element
A method of transmitting data, comprising:
- providing a transceiver having an interface unit to receive and transmit signals,
- transmitting a first signal comprising first data via said interface unit,
- receiving a second signal at said interface unit,
- determining an indicator of corruption of said second signal, and
- retransmitting said first data based on said indicator.
2 more elements
A transceiver, comprising:
- an interface unit to transmit a first signal comprising first data and to receive a second signal,
- a monitoring unit coupled to said interface unit to determine an indicator of corruption of said second signal, and
- a retransmission controller coupled to said monitoring unit to receive said indicator and coupled to said interface unit to initiate retransmission of said first data based on said indicator.
