Abstract

The present invention is a receiver having a radio frequency (RF) front end, a pulse detector operatively coupled to the RF front end, and a data recovery unit operatively coupled to the pulse detector. The data recovery unit is configured to receive spread spectrum RF signals having different pulse repetition frequencies and using different modulation techniques. The receiver may operate in conjunction with a transmitter as a transceiver. The receiver may also operate in a networked environment in which a network of transceiver node devices comprise a first slave transceiver having a receiver configured to receive spread spectrum signals, and a second slave transceiver configured to communicate with the first slave transceiver. Additionally, a master transceiver is in communication with the first slave transceiver and the second slave transceiver. The master transceiver is configured to manage data transmissions and synchronization between the first slave transceiver and the second slave transceiver.

Claims

1. A network of transceiver node devices comprising:

a first slave transceiver having a receiver configured to receive ultra-wideband spread spectrum signals;

a second slave transceiver configured to communicate with said first slave transceiver; and

a master transceiver in communication with said first slave transceiver and said second slave transceiver, said master transceiver configured to manage data transmissions and synchronization between the said first slave transceiver and said second slave transceiver by using ultra-wideband spread spectrum signals, the master transceiver comprising a master receiver including a radio frequency (RF) front end, a pulse detector operatively coupled to said RF front end, and a data recovery unit configured to receive spread spectrum RF signals having variable pulse repetition frequencies.
