Abstract
A jamming or MAS system is provided having multiple transmit antennas for transmitting respective transmit signals with spatial diversity to reduce multipath fading. The jamming or MAS communication system communicates with at least one receiver for receiving the transmit signals with no additional processing required at the receiver. In some embodiments, the jamming or MAS communication system includes an associated receiver for receiving and analyzing various signals. The jamming or MAS communication system in the present invention is able to help reduce the effects of multipath fading without modifications to the receiver. Prior art attempts to reduce the effects of multipath fading require some form of additional processing at the receiver. The invention is particularly useful when deployed in a Managed Access Service (MAS) system or a jamming system. In particular, such a system can be used in a facility (such as a prison, school, government building, etc) to prevent cellphone usage.
