Stochastic Resonance Assisted Successive Interference Cancellation Receiver for Signal Detection Performance Improvement

Performance Improvement Technique for Multiuser Detection in DS-CDMA Systems Using Successive Interference Cancellation

Multiple access interference (MAI) limits the capacity of Direct sequence Code Division Multiple Access (DS-CDMA) systems. In CDMA systems MAI is considered as additive noise and matched filter bank is employed. Traditionally, multiuser detectors a code matched and a multiuser linear filter are used which increases the complexity of the system due to its nature of operation. Multiuser detection...

Group-wise successive interference cancellation receiver with adaptive MMSE detection for dual-rate DS-CDMA system

In this paper, group-wise successive interference cancellation (GSIC) receiver with adaptive minimum mean squared error (MMSE) detection and extended GSIC (EGSIC) receiver with adaptive MMSE detection are proposed for dualrate DS-CDMA system. Users are divided into 2 groups for their data rates: high-rate (HR) users and low-rate (LR) users. Initial bit estimates for the HR users are obtained by...

Successive Interference Cancellation Based Signal Detector for Wireless MIMO Communications

Performance Improvement Technique for Multiple User Detection in DS-CDMA System using Groupwise Successive Interference Cancellation (GSIC)

Code Division Multiple Access (CDMA) system is being most popular communication technique due to its robustness & spread spectrum techniques. The CDMA include the pseudo sequences (PN-sequences) which provide the secure communication over a wide band. But the Multiple Access Interference (MAI) limits the capacity of Direct Sequence Code Division Multiple Access (DS-CDMA) based systems. For DS-C...

Successive Interference Cancellation for MIMO UW-OFDM

Unique word orthogonal frequency division multiplexing (UW-OFDM) is a new signaling concept which has better spectral properties and also a superior bit error ratio (BER) performance over conventional cyclic prefix (CP) based OFDM. In UW-OFDM, the CPs are replaced by deterministic sequences, the so-called unique words (UWs). So far, the performance of UW-OFDM has been well investigated for sing...
