Efficient Complex Sphere Decoding for MC-CDMA Systems [PDF]
IEEE Transactions on Wireless Communications, 2006 Maximum likelihood (ML) joint detection of multi-carrier code division multiple access (MC-CDMA) systems can be efficiently implemented with a sphere decoding (SD) algorithm. In this paper, we examine the application of complex instead of real SD to detect MC-CDMA, which solves many problems in a more elegant manner and extends SD adaptability to any ...

Adaptivity in MC-CDMA Systems [PDF]
, 2006 This paper investigates the performance of MC-CDMA with link adap- tation in the uplink of a wireless communication system. Two types of link adaptation approaches can be distinguished: 1) Exploitation of channel state information (CSI) at the transmitter and 2) exploitation of CSI at both the transmitter and the receiver.

Blind Linear MMSE Receivers for MC-CDMA Systems [PDF]
IEEE Transactions on Circuits and Systems I: Regular Papers, 2007 This paper studies blind constrained minimum output energy (CMOE)-based and subspace-based linear minimum mean-squared-error (LMMSE) detectors for multi-carrier code division multiple access (MC-CDMA) systems. By imposing quadratic weight constraint, the CMOE detector is made more robust against signature waveform mismatch, and a better performance ...
