GPS NEAR-FAR RESISTANT RECEIVER

Title:

GPS NEAR-FAR RESISTANT RECEIVER

Document Type and Number:

WIPO Patent Application WO2003023444

Kind Code:

B1

Abstract:

A method and receiver are disclosed for mitigating or substantially canceling signal interference between signals detected at the receiver. Once a presumed interfering signal(s) is acquired, parameters are determined that allow the interferer(s) to be modeled. An orthogonal projection (for projecting onto a subspace spanned by the interfere(s) is applied to the composite of all signals (y) for thereby projecting y onto this subspace, wherein the subspace is non-orthogonal to a representation of desired (but interfered) signal of the composite signals. With the receiver properly equipped to perform this projection operation, interfering signals, multipath, spoofing and/or meaconing can be effectively diminished.
