  4. Abstract:
  5. In this paper, we consider an iterative multiuser receiver for the coded MC-FH system, first introduced in [4], in the presence of partial-band interference. The structure of the receiver consists of two principal parts: multiuser soft input soft output (SISO) detector and SISO channel decoder. When the channel is under the attack of jamming, for optimum detection we propose to add a jamming estimator to multiuser SISO detector. So, the new SISO multiuser detector consists of multiuser likelihood calculator (MULC) and iterative jamming estimator (JE). The numerical results show that the proposed receiver works quite well compared to the ideal receiver which has the perfect channel state information (CSI). Further more, for the low number of users, the proposed receiver outperforms the receiver with perfect CSI. © 2004 IEEE
