The Synthesis of TD-Sequences and Their Application to Multi-functional Communication Systems

The multi-functional approach to design has been previously defined. This paper emphasizes the need for such approach in order to reduce the increasing level of complexity of future communication systems. The paper then describes a class of deterministic quasi-analogue (multi-level) pseudorandom sequences with good correlation properties and the means for tailoring the sequences' probability density functions. Finally, the family of sequences is shown to offer a vehicle for coalescing a number of aspects of multi-functionality within the context of spread-spectrum communication systems.
