Abstract

A wireless monitoring receiver and system use multiple video data feeds from a plurality of cameras. The video feeds are transmitted using a multi-antenna technique, and decoded by a multi-antenna processor. The resulting transmissions are resistant to noise, interference, etc., and can be focused using antenna beams to achieve a simple form of location encryption.

Claims

1. A method comprising:

receiving signals transmitted from a first location at a second location, the signals comprising M independently-modulated data-bearing signals;

processing the M independently-modulated signals using a channel matrix and a separately recovered data signal to extract the data from the data-bearing signals; and

storing the data from the data-bearing signals.

2. The method according to claim 1, further comprising:

processing the data transmitted from N radio module transmitters simultaneously.

3. The method according to claim 1, further comprising:

receiving the data transmitted via N separate antennas simultaneously as N separate bit streams.

4. The method according to claim 1, wherein the data from the data-bearing signals includes video data.

5. An apparatus comprising:

means for receiving signals transmitted from a first location at a second location, the signals comprising M independently-modulated data-bearing signals;

means for processing the M independently-modulated signals using a channel matrix and a separately recovered data signal to extract the data from the data-bearing signals; and

means for storing the data from the data-bearing signals.

6. The apparatus according to claim 5, further comprising:

means for processing the data-bearing signals received from N radio module transmitters simultaneously.

7. The apparatus according to claim 5, wherein the data-bearing signals correspond to signals transmitted via N separate antennas simultaneously as N separate bit streams.

8. The apparatus according to claim 5, wherein the data from the data-bearing signals includes video data.

9. An apparatus comprising:

at least two receiving modules to receive signals transmitted from a first location at a second location, the signals comprising M independently-modulated data-bearing signals; and

a processing module to process the M independently-modulated signals using a channel matrix and a separately recovered data signal to extract the data from the data-bearing signals.

10. The apparatus according to claim 9, wherein the processing module includes:

at least two Fourier transform processors coupled to process outputs from the at least two receiving modules; and

a matrix multiplier coupled to process outputs of said Fourier transform processors.

11. The apparatus according to claim 10, wherein the matrix multiplier is further to receive said separately recovered data signal.

12. The apparatus according to claim 9, wherein the data-bearing signals are to be received from N radio module transmitters simultaneously.

13. The apparatus according to claim 9, wherein the data-bearing signals correspond to signals transmitted via N separate antennas simultaneously as N separate bit streams.

14. The apparatus according to claim 9, wherein the data from the data-bearing signals includes video data.
