Patent ID: 8149879

Claim:
A method of data transmission, said method comprising: encoding, using an encoder, a plurality of data values into a symbol; transmitting a plurality of bursts using a transmitter, each burst occupying one of a plurality of frequency bands; wherein at least an order of transmission of the plurality of bursts in time and a polarity of at least one of the plurality of bursts defines the symbol, the symbol corresponding to the plurality of data values; wherein a bandwidth of at least one of the plurality of bursts is at least two percent of a center frequency of the burst; wherein said plurality of bursts includes a first burst occupying one of the plurality of frequency bands and a second burst occupying a different one of the plurality of frequency bands, and wherein at least one frequency point exists at which the amplitude of the first burst is within twenty decibels of a maximum amplitude of the first burst and at which the amplitude of the second burst is within twenty decibels of a maximum amplitude of the second burst.
