发明名称 Spread spectrum conferencing communication system
摘要 An anti-jam PN sequence spread spectrum conferencing communication system is disclosed for simultaneously transmitting and receiving in a plurality of communications channels secure voice communications. All received messages are modulated with the same pseudo noise sequence and arrive at any given channel at random time states, wherein the messages are separated, separately processed and finally conferenced, using a technique based upon the correlation of the PN sequence and dependent upon the randomness of the epoch state of a given PN sequence coded with a message in relation to the other coded messages.
