Abstract
Multiple cochannel AM signals received in an overloaded signal environment may be separated using RF data through a method of iterative projections.
Claims27
A method for processing AM signals, comprising:
- receiving RF data in an overloaded signal environment, said received RF data comprising cochannel AM signals received in the same frequency range and at the same time;
- and
- separating each of said cochannel AM signals from other cochannel AM signals of said received RF data.
A method for transmitting AM signals, comprising providing RF data comprising cochannel AM signals for transmission in the same frequency range and at the same time for reception by a receiver operating in an overloaded signal environment, said receiver configured to separate each of said cochannel AM signals from other cochannel AM signals of said RF data.
A system for communication using an overloaded signal environment, said system comprising:
- transmit circuitry configured to provide RF data comprising cochannel AM signals for transmission in the same frequency range and at the same time;
- and
- receive and separation circuitry configured to receive and separate each of said cochannel AM signals from other cochannel AM signals of said RF data.
An AM signal processing system, comprising:
- receive and separation circuitry coupled to receive RF data from at least one sensor operating in an overloaded signal environment, said received RF data comprising cochannel AM signals received in the same frequency range and at the same time;
- and
- wherein said receive and separation circuitry is configured to separate each of said cochannel AM signals from other cochannel AM signals of said received RF data.
