Abstract
System and method for signal processing and beam forming. A system for processing signals includes a first phase shifter, a second phase shifter, a first variable time delay system, and a second variable time delay system. Additionally, the system includes a first signal processing system and a sampling system. Moreover, the system includes a switching system and a measuring system.
Claims14
A system for processing signals, the system comprising:
- a first phase shifter configured to receive or generate a first signal;
- a second phase shifter configured to receive or generate a second signal;
- a first variable time delay system coupled to the first phase shifter and configured to generate or receive a third signal;
- a second variable time delay system coupled to the second phase shifter and configured to generate or receive a fourth signal;
- a first signal processing system coupled to the first variable time delay system and the second variable time delay system and configured to generate or receive a fifth signal;
- a sampling system configured to sample at least the third signal and the fourth signal and generate at least a sixth signal and a seventh signal respectively;
- a switching system configured to receive the at least a sixth signal and a seventh signal and output an eighth signal and a ninth signal, the eighth signal being the same as one of the at least a sixth signal and a seventh signal, the ninth signal being the same as one of the at least a sixth signal and a seventh signal;
- a measuring system configured to receive the eighth signal and the ninth signal and process at least information associated with the eighth signal and the ninth signal.
