摘要：
A spread spectrum system may include a transmitter and a receiver. The transmitter is configured to transmit a signal having at least one channel, where the signal may include a reference signal, an information signal and a frequency offset between the reference signal and the information signal. The receiver may receive the transmitted signal from the transmitter and mix the received signal in order to retrieve the information signal from the received signal. This allows the receiver to operate at low power (e.g., 10 uW-100 uW).
