Multiple-input multiple-output wireless communication apparatus and method
Disclosed herein is a multiple-input multiple-output (mimo) wireless communication apparatus including: a plurality of radio frequency (rf) modules each processing rf signals input; a plurality of local area communication modules processing a local area communication signal input; a plurality of switches; and a control block determining whether there is an idle rf module in the plurality of rf modules at the time of the mimo mode operation and switching a corresponding switch so that the local area communication module operating in the mimo mode and a corresponding rf antenna corresponding to the idle rf module are connected to each other. Therefore, the mimo mode is implemented without adding the local area communication dedicated antenna, thereby making it possible to maximize space utilization and reduce a cost..

Gps independent guidance sensor system for gun-launched projectiles
A sensor system uses ground emitters to illuminate a projectile in flight with a polarized rf beam. By monitoring the polarization modulation of rf signals received from antenna elements mounted on the projectile, both angular orientation and angular rate signals can be derived and used in the inertial solution in place of the gyroscope.
