  1. Multiple-access interference and interfinger interference limit the capacity of conventional single-carrier DS-CDMA systems. Even though multicarrier CDMA posses the advantages of conventional CDMA and OFDM, i...

    Citation: EURASIP Journal on Wireless Communications and Networking 2004 2004:862051
  2. We investigate rotated Walsh-Hadamard spreading matrices for a broadband MC-CDMA system with robust channel estimation in the synchronous downlink. The similarities between rotated spreading and signal space d...

    Authors: Ronald Raulefs, Armin Dammann, Stephan Sand, Stefan Kaiser and Gunther Auer
    Citation: EURASIP Journal on Wireless Communications and Networking 2004 2004:713902
  3. We design multilevel coding (MLC) with a semi-bit interleaved coded modulation (BICM) scheme based on low density parity check (LDPC) codes. Different from the traditional designs, we joined the MLC and BICM t...

    Citation: EURASIP Journal on Wireless Communications and Networking 2004 2004:709437
  4. The paper considers downlink space-frequency preequalizations techniques for time division duplex (TDD) MC-CDMA. We consider the use of antenna arrays at the base station (BS) and analytically derive different...

    Citation: EURASIP Journal on Wireless Communications and Networking 2004 2004:706371
  5. Although numerous channel estimation and multiuser detection approaches have appeared for long-code uplink CDMA systems, joint performance study of channel estimators and symbol detectors remains largely open....

    Authors: Ping Liu and Zhengyuan Xu

  6. This paper proposes a two-stage maximum likelihood estimation (TSMLE) technique suited for multitone code division multiple access (MT-CDMA) system. Here, an analytical framework is presented in the indoor env...

    Authors: Quazi Mehbubar Rahman, Abu B Sesay and Mostafa Hefnawi
    Citation: EURASIP Journal on Wireless Communications and Networking 2004 2004:601464
  7. 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...

    Authors: Giacinto Gelli, Luigi Paura and Francesco Verde
    Citation: EURASIP Journal on Wireless Communications and Networking 2004 2004:458564
  8. 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...

    Authors: Jeongsoon Park, Jong-Han Lim and Saul B Gelfand
    Citation: EURASIP Journal on Wireless Communications and Networking 2004 2004:345156
  9. 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...

    Authors: Quang Hieu Dang and Alle-Jan van der Veen
    Citation: EURASIP Journal on Wireless Communications and Networking 2004 2004:327410
  10. While mobile hosts are evolving into full-IP enabled devices, there is a greater demand to provide a more flexible, reconfigurable, and scalable security mechanism in mobile communication systems beyond 3G (B3...

    Authors: Georgios Kambourakis, Angelos Rouskas and Stefanos Gritzalis
    Citation: EURASIP Journal on Wireless Communications and Networking 2004 2004:314541
  11. Wireless code-division multiple-access (CDMA) cellular downlink communications with transmit antenna arrays in multipath fading channels is studied. Various array signal processing techniques at the transmit e...

    Authors: Huaiyu Dai, Laurence Mailaender and HVincent Poor
    Citation: EURASIP Journal on Wireless Communications and Networking 2004 2004:219825
  12. An algorithm for designing spreading sequences for an overloaded multicellular synchronous DS-CDMA system on uplink is introduced. The criterion used to measure the optimality of the design is the total weight...
