  4. We extend three types of overloaded CDMA systems, by displacing in time the binary signature sequences of these systems: (1) random spreading (PN), (2) multiple-OCDMA (MO), and (3) PN/OCDMA (PN/O). For each of...

    Citation: EURASIP Journal on Wireless Communications and Networking 2004 2004:601464
  12. We consider the problem of blind (i.e., without training sequences) linear mitigation of multiple-access interference in the uplink of quasi-synchronous multicarrier code-division multiple-access (MC-CDMA) sys...

    Citation: EURASIP Journal on Wireless Communications and Networking 2004 2004:458564
  13. When combining a multicode CDMA system with convolutional coding, two methods have been considered in the literature. In one method, coding is across time in each multicode channel while in the other the codin...

    Citation: EURASIP Journal on Wireless Communications and Networking 2004 2004:345156
  14. Receivers for long-code systems are for computational reasons usually based on simple matched-filter techniques, and hence suffer from multiaccess interference. Decorrelating RAKE and MMSE receivers do not hav...
