Abstract
A method and system for transmitting and receiving a control data signal within spreading signal and an intelligence/analog signal. The control data is interleaved within the spreading data signal at a transmitter side. Before transmitting to a remote receiver side, the spreading/control data signal, after passing a high-pass filter, and an intelligence signal, which is passing through a low-pass filter, are summed by a summing device to form a composite intelligence/spreading data (CISS)signal and are modulated on an RF carrier by a modulator. After receiving the CISS modulated RF carrier, the receiver side converses the CISS modulated RF carrier to IF signal, which is then demodulated by a demodulator to recover the original CISS signal. The CISS signal is then passing through a low-pass filter to recover the intelligence signal and through a high-pass filter to recover the spreading/control signal. The control signal is further recovered by a digital device.
