THE RESEARCH OF A NEW MULTIUSER DETECTION SCHEME COMBINING DECORRELATING DETECTOR AND PARTIAL PARALLEL INTERFERENCE CANCELLER

International Telemetering Conference Proceedings / October 18-21, 2004 / Town & Country Resort, San Diego, California / The decorrelating detector can afford good data estimates because it does not need to know many
parameters of the received signal. However, it shows great performance deprivation when the
background noise is high. On the other hand, partial parallel interference canceller(PPIC) has the
potential to combat the near-far problem and have much lower computation complexity. But its
performance depends on the initial data estimate. An improved PPIC scheme is proposed in this
paper to combat the near-far problem. It utilizes the advantages of the two detectors by combining
them. The focus of this paper is on the BER performance and the near-far resistance capability of the
proposed scheme. Computer simulations demonstrate that the proposed detector has good BER
performance and near-far resistance capability.
