Abstract
The present invention relates to the field of communications. The method includes generating a sequence of symbols, the sequence of symbols including preamble symbols and a data symbol. The method further includes receiving the sequence of symbols generated by the transmitter, the receiver including a frame synchronizer logic to perform frame synchronization.
Claims12
A system comprising:
- a transmitter in a first network node to generate a sequence of symbols, the sequence of including preamble symbols and a data symbol, a last preamble symbol in the sequence of symbols having a different waveform than other preamble symbols in the sequence of symbols;
- and
- a receiver in a second network node to receive the sequence of symbols generated by the transmitter, the receiver including a frame synchronizer logic to perform frame synchronization.
A system comprising:
- a transmitter in a first network node to generate a sequence of symbols, the sequence of including preamble symbols and a data symbol, a waveform of a last preamble symbol in the sequence of symbols is different than waveforms of other preamble symbols in the sequence of symbols;
- and
- a receiver in a second network node to receive the sequence of symbols generated by the transmitter, the receiver including a frame synchronizer logic to perform frame synchronization.
A method comprising:
- generating a sequence of symbols, the sequence of symbols including preamble symbols and data symbol;
- using a second waveform to represent a last preamble symbol in the sequence of symbols and a first waveform to represent other preamble symbols in the sequence of symbols, wherein the second waveform is substantially different than the first waveform;
- and
- receiving the sequence of symbols generated by the transmitter, the receiver including a frame synchronizer logic to perform frame synchronization.
1 more element
A machine-readable medium comprising instructions which, when executed by a machine, cause the machine to perform operations comprising:
- generating a sequence of symbols, the sequence of symbols including preamble symbols and a data symbol, a last preamble symbol in the sequence of symbols having a different waveform than other preamble symbols in the sequence of symbols;
- and
- receiving the sequence of symbols generated by the transmitter, the receiver including a frame synchronizer logic to perform frame synchronization.
