First Claim
1. An extensible communication system, comprising:
- a memory storing program instructions; and
a processor, upon executing the program instructions, configured to;
select a root index value to signal to a receiver device a major version number, wherein the major version number corresponds to a service type or mode that is to be communicated to the receiver device;
generate a constant amplitude zero auto-correlation sequence based on the selected root index value;
select a seed value to signal to the receiver device a minor version number within the major version number;
generate a Pseudo-Noise sequence based on the selected seed value;
modulate the constant amplitude zero auto-correlation sequence by the Pseudo-Noise sequence and generate a complex sequence; and
translate the complex sequence to a time domain sequence.

Abstract
An extensible communication system is described herein. The system includes a first module for receiving a root index value and for generating a constant amplitude zero auto-correlation sequence based on the root value. The system further includes a second module for receiving a seed value and for generating a Pseudo-Noise sequence based on the seed value. The system further includes a third module for modulating the constant amplitude zero auto-correlation sequence by the Pseudo-Noise sequence and for generating a complex sequence. The system further includes a fourth module for translating the complex sequence to a time domain sequence, wherein the fourth module applies a cyclic shift to the time domain sequence to obtain a shifted time domain sequence.
