Abstract
An encoder uses orthogonal dispersion sequences to encode symbols of an applied symbol stream as a series of microbursts that are separated by variable time intervals established by the time dispersion sequences. A decoder selects one or more series of microbursts from a composite set of microbursts received by the decoder, based on dispersion sequences at the decoder that match the dispersion sequences used to encode the one or more series of microbursts. Each selected series of microbursts is then conditioned to extract a corresponding symbol stream.
Claims20
A symbol encoder, comprising:
- a series of variable time interval samplers receiving corresponding symbol streams that are synchronous each other;
- and
- one or more time dispersion code generators providing a corresponding dispersion sequence to each of the variable time interval samplers in the series to activate the variable time interval samplers to each generate a corresponding series of microbursts coherent with the received symbol streams and separated by varying time intervals established by the provided dispersion sequences, wherein the dispersion sequences are orthogonal.
A symbol encoding method, comprising:
- receiving one or more synchronized symbol streams;
- and
- representing each of the symbol streams by a corresponding series of microbursts wherein the microbursts within each series are separated by variable time intervals established by a corresponding dispersion sequence.
A symbol decoder, comprising:
- a series of variable time interval samplers receiving a composite set of microbursts including one or more series of microbursts each encoded at a corresponding burst rate, the microbursts within each of the multiple series separated by varying time intervals;
- a set of time dispersion code generators synchronized to the burst rate, providing a corresponding dispersion sequence to each of the variable time interval samplers in the series and driving the variable time interval samplers in the series to each select microbursts from the composite set of microbursts designated according to the corresponding dispersion sequence, wherein the dispersion sequences are orthogonal;
- and
- a conditioner receiving the selected microbursts from the composite set of microbursts and extracting a corresponding symbol stream.
A symbol decoding method, comprising:
- receiving a composite set of microbursts encoding one or more symbol streams;
- selecting one or more series of microbursts from the received composite set of microbursts, wherein the microbursts within each of the one or more series of microbursts are separated by variable time intervals established by corresponding dispersion sequences that are orthogonal;
- and
- conditioning the selected one or more series of microbursts to extract from each of the one or more series of microbursts a corresponding one of the encoded symbol streams.
