Abstract

A digital modulation system and method is provided. The present invention employs a communication frame that includes a synchronization section. In addition to providing synchronization function(s), one embodiment of the present invention modulates, or encodes data onto the synchronization section. By using the synchronization section to carry additional data, the amount of data transmitted with each frame is increased. This increases the bandwidth of communication system employing the method of the present invention. This Abstract is provided for the sole purpose of complying with the Abstract requirement rules that allow a reader to quickly ascertain the subject matter of the disclosure contained herein. This Abstract is submitted with the explicit understanding that it will not be used to interpret or to limit the scope or the meaning of the claims.

Claims

1. A modulation method, the method comprising the steps of:

generating a communication frame, the frame including a synchronization section; and

encoding data onto the synchronization section.

2. The modulation method of claim 1, wherein the step of encoding data is performed before the step of generating the communication frame.

3. The modulation method of claim 1, further comprising the steps of:

transmitting the communication frame;

receiving the communication frame; and

decoding the data from the synchronization section.

4. The modulation method of claim 1, wherein the synchronization section is located in a preamble section of the communication frame.

5. The modulation method of claim 1, wherein the communication frame further comprises a data section and a trailer section.

6. The modulation method of claim 1, wherein the synchronization section comprises a first orthogonal code and a second orthogonal code, with the second orthogonal code comprising a reverse polarity of the first orthogonal code.

7. The modulation method of claim 1, wherein the communication frame is transmitted using a plurality of discrete electromagnetic pulses, with each pulse having a duration that ranges between about 10 picoseconds to about 1 millisecond.

11. A communication method, the method comprising the steps of:

generating at least two communication frames, with each frame including a preamble section containing at least one individual binary code;

encoding data to the individual binary codes;

transmitting the communication frames;

receiving the communication frames;

grouping the individual binary codes; and

obtaining data from the grouped binary codes.

12. The communication method of claim 11, wherein the step of encoding data to the individual binary codes comprises assigning a set of bits to the individual binary codes of the preamble sections.
