US Patent:

6356580, Mar 12, 2002

Filed:

Jul 6, 1999

Appl. No.:

09/348740

Inventors:

Robert S. Parks - Fairborn OH

Assignee:

The United States of America as represented by the Secretary of the Air Force - Washington DC

International Classification:

A61F 206

US Classification:

375141

Abstract:

A reception simplified, reduced cost spread spectrum transceiver device and method. The transmitting portion of the transceiver antipodally modulates a pseudorandom code and non-antipodally modulates binary bit data onto a carrier wave. The receiving portion of the transceiver performs a mathematical squaring function on the received signal combination of pseudorandom code and data. Squaring the pseudorandom code results in a cancellation of the code and the data remains in the absence of the pseudorandom code. The device and method of the invention eliminates the need for storing or generating a local reference for the spreading code or the need for any knowledge of key signal parameters at the receiver greatly simplifying receiver circuitry and allowing receiver operation at low energy density and low operational cost. Additionally, the device and method of the invention eliminates the synchronization constraint between the transmitted data and spreading code of conventional systems.
