Spread spectrum conference call system and method

A method for receiving spread-spectrum conference calls, comprising the steps of:

• recovering, using a replica of a generic-chip-code signal, a carrier signal from a spread-spectrum-communications signal;
• acquiring and tracking the recovered-carrier signal;
• generating the replica of the generic-chip-code signal synchronized to the recovered-carrier signal;
• generating a replica of the message-chip-code signal;
• synchronized to the replica of the generic-chip-code signal;
• despreading, using the replica of the message-chip-code signal, the spread-spectrum-communications signal as a modulated-data signal;
• synchronizing the replica of the generic-chip-code signal to the recovered carrier signal;
• and
• demodulating the modulated-data signal as received data.

A spread-spectrum conference calling communications system for simultaneously listening to a plurality of spread-spectrum channels of a spread-spectrum-communications signal comprising:

• generic-spread-spectrum-processing means for recovering a carrier signal from the spread-spectrum-communications signal and for generating a replica of a generic-chip-code signal;
• and
• a plurality of spread-spectrum receivers, each of said spread-spectrum receivers including,
• acquisition means responsive to acquiring and tracking the recovered carrier signal for synchronizing said generic-spread-spectrum-processing means to the recovered carrier signal;
• message-spread-spectrum-processing means for despreading the spread-spectrum-communications signal as a plurality of modulated-data signals;
• and
• demodulation means for demodulating the modulated-data signal as a demodulated signal.

A spread-spectrum conference calling communications system for simultaneously listening to a plurality of spread-spectrum channels of a spread-spectrum-communications signal comprising:

• a receiver-generic-chip-code generator for recovering a carrier signal from the spread-spectrum-communications signal and for generating a replica of a generic-chip-code signal;
• and
• a plurality of spread-spectrum receivers, each of said spread-spectrum receivers including,
• an acquisition and tracking circuit, responsive to acquiring and tracking the recovered carrier signal, for synchronizing said receiver-generic-chip-code generator to the recovered carrier signal;
• a receiver-message-chip-code generator for despreading the spread-spectrum-communications signal as a plurality of modulated-data signals;
• and
• demodulation means for demodulating the modulated-data signal as a demodulated signal.
