Research abstract

AN IMPROVED DEMODULATOR STRUCTURE HAS BEEN CONCEIVED FOR SPREAD SPECTRUM CODE DIVISION MULTIPLE ACCESS COMMAND, CONTROL, AND COMMUNICATIONS NETWORKS. THIS STRUCTURE PROMISES MUCH GREATER SEPARABILITY OF THE CDMA SIGNALS THAN CAN BE ACHIEVED WITH A CONVENTIONAL DEMODULATOR. ITS BENEFITS WILL BE MOST NOTABLE IN BEING ABLE TO DEMODULATE VERY WEAK SIGNALS IN THE PRESENCE OF VERY STRONG SIGNALS (THE SO-CALLED NEAR/FAR PROBLEM), WHERE THE RATIO OF SIGNAL STRENGTHS MAY BE MUCH LARGER THAN THE BANDWIDTH SPREADING RATIO.
