[UK-CONTEST] 4 square simululator

[Mark Marsden]

A four-square simulator is now available as a free download. This is a
spin-off from work done by Plextek for Ofcom's SMART antenna program for
beam and null steering.

It provides a real time display of the polar diagram and signal to noise
ratio of multiple wanted signals and unwanted interferers.  Playing
around with the direction of the signals and watching the weighting
coefficients optimise gives valuable insight into what a four square can
do. Changing the array size is most revealing.

Visit http://www.plextek.co.uk/downloads.htm  and click on "SMART
Antenna Demonstration".   A 1.4MB zip file is opened from which you can
install the simulator.
    
Enjoy.
