Abstract
A system for receiving, correlating and interpreting secured wireless transmissions, periodic or otherwise, including multiplexed receivers, robust correlator design, a state machine device for controlling the receivers and correlation function, and the ability to determine signal spatial diversity via switched antenna signal processing. The correlator is constructed to include a synchronization scheme adaptive to any variety of input signals from the coupled receiver tuned frequencies.
Claims13
A system for receiving and processing transmitted signals, comprising:
- an antenna;
- a plurality of receivers coupled to the antenna and tunable to the frequencies upon which the signal is transmitted;
- a correlator for obtaining synchronization between the receivers and the transmitted signals;
- a first switch disposed between the receivers and the correlator thereby coupling each receiver to the correlator;
- a state device coupled to the correlator and the receivers that provides an enabling signal to the receiver and a corresponding decode mask to the correlator for synchronizing the transmitted signal;
- and
- a code generator coupled to the state device providing a predetermined code sequence for use in obtaining system synchronization.
A system for receiving and processing frequency-hopped transmitted signals, comprising:
- an antenna array having switchable elements physically mounted in alternate locations;
- a plurality of receivers coupled to the antenna array and tunable to the frequencies that the signal is transmitted;
- a correlator for obtaining synchronization between the receivers and the transmitted signals;
- a first switch disposed between the receivers and the correlator thereby coupling each receiver to the correlator;
- additional processing means coupled to the correlator output signal;
- a second switch disposed between and coupled to each of the receivers and antenna elements;
- a state device coupled to the correlator, the receivers, and the antenna elements that provides an enabling signal to one or more of the antenna elements, the receivers and a corresponding decode mask to the correlator for synchronizing the transmitted signal;
- and a code generator coupled to the state device providing a predetermined code sequence for use in acquiring system synchronization.
