EURASIP Journal on Advances in Signal Processing, 2003 The goal of this paper is to compare the performance of the linear minimum mean square error (MMSE) detector for a class of code division multiple access (CDMA) systems in time and frequency selective channels. Specifically, we consider direct sequence (

Adaptive TORC detection for MC-CDMA wireless systems
IEEE Transactions on Communications, 2009 Multi carrier code-division multiple access (MC-CDMA) is considered for beyond third generation wireless systems for its effectiveness in the presence of both multipath fading and interference. This paper analyzes MC-CDMA systems adopting an adaptive detection technique based on threshold orthogonality restoring combining (TORC).

Sensitivity of Multicarrier Two-Dimensional Spreading Schemes to Synchronization Errors
EURASIP Journal on Wireless Communications and Networking, 2008 This paper presents the impact of synchronization errors on the performance of a downlink multicarrier two-dimensional spreading OFDM-CDMA system. This impact is measured by the degradation of the signal to interference and noise ratio (SINR) obtained ...

Blind Identification and Equalization of MC-CDMA Systems Using Higher Order Cumulants
International Journal of Advances in Telecommunications, Electrotechnics, Signals and Systems, 2014 In this work we propose an algorithm based on fourth order cumulants for identification of the linear system (Finite- Impulse Response (FIR)) with Non Minimum Phase (NMP) excited by non-Gaussian sequences, independent identically distributed (i.i.d).

Joint turbo equalization and multiuser detection of MC-CDMA signals with low envelope fluctuations [PDF]
, 2008 In this paper, we consider the uplink transmission in multicarrier code-division multiple-access (MC-CDMA) systems. As other multicarrier signals, MC-CDMA signals have high envelope fluctuations and a high peak-to-mean envelope power ratio (PMEPR), which

On Analyzing LDPC Codes over Multiantenna MC‐CDMA System
Mathematical Problems in Engineering, 2014 Multiantenna multicarrier code‐division multiple access (MC‐CDMA) technique has been attracting much attention for designing future broadband wireless systems. In addition, low‐density parity‐check (LDPC) code, a promising near‐optimal error correction code, is also being widely considered in next generation communication systems.
