Abstract

A system and method of applying a known modification in the form of a distortion to a signal to enable a determination if a signal received by a first node is received directly from a second node or indirectly through a repeater. The repeater receives a primary signal and creates a secondary signal as a function of the primary signal and a known distortion, wherein the known distortion identifies the repeater. The primary signal is transmitted and injected with the secondary signal as the first signal to the primary receiver.

Claims (10)

1. A communication system comprising:

a first node including a transmitter for transmitting a first signal;

a repeater comprising:

a receiver for receiving said first signal;

circuitry for creating a known distortion signal and combining said distortion signal with said received first signal to thereby form a combined signal, wherein said distortion signal identifies said repeater; and

a transmitter for transmitting said combined signal;

a second node comprising a receiver for receiving a received signal from either said first node or said repeater; and

circuitry for determining if said received signal is said first signal or said combined signal.

2. The system of claim 1 wherein the communication system is a wireless communication system.

3. The system of claim 1 wherein the second node is a mobile unit.
