Description:
BACKGROUND

1. Field

This disclosure relates to methods and systems for improving noise-isolation/cross coupling of communication systems.

2. Background

The conventional approach for achieving multiple communications functions is to use different antennas with each antenna providing for one function. In such a configuration, these antennas should be spaced far enough apart physically so that electromagnetic isolation between systems may be achieved by the virtue of the spatial distance.

Unfortunately, this approach may not be available in small environments, such as aircraft and ships, where space is limited and a large variety of functions are necessary for efficient operation. Accordingly, new technology related to the integration of communication systems is desirable.

SUMMARY

Various aspects and embodiments of the invention are described in further detail below.

In a first series of embodiments, a compensation . . . . More
Abstract:
A compensation apparatus for an integrated communication system is disclosed. The integrated communication system can include a first communication device having a first transmitter antenna, and a second communication device having a second receiver antenna, wherein the second receiver antenna is in appreciable proximity of the first transmitter antenna such that the second receiver antenna picks up substantial electromagnetic interference from the first communication device. The compensation apparatus can include an isolation device having compensation circuitry coupling the first transmitter antenna and the second receiver antenna and configured to adaptively cancel the electromagnetic interference from the first communication device at the second receiver antenna.
Claims:
What is claimed is:

1. A compensation apparatus for an integrated communication system, the integrated communication system having a first communication device including a first transmitter antenna, and a second communication device including a second receiver antenna, wherein the second receiver antenna is in appreciable proximity of the first transmitter antenna such that the second receiver antenna picks up electromagnetic interference from the first communication device, the compensation apparatus comprising: an isolation device having compensation circuitry coupling the first transmitter antenna and the second receiver antenna and configured to adaptively cancel the electromagnetic interference from the first communication device at the second receiver antenna.

2. The apparatus of claim 1, wherein the compensation circuitry includes an amplification device configured to adaptively change an amplitude of a transmitter compensation signal to the second receiver an . . . . More
