Improved Multiple Feedback Successive Interference Cancellation Algorithm for Near-Optimal MIMO Detection

In this article, we propose an improved multiple feedback successive interference cancellation (IMF-SIC) algorithm for symbol vector detection in multiple-input multipleoutput (MIMO) spatial multiplexing systems. The multiple feedback (MF) strategy in successive interference cancellation (SIC) is based on the concept of shadow area constraint (SAC) where, if the decision falls in the shadow reg...

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...

Power control for successive interference cancellation with imperfect cancellation

This paper proposes and analyzes an iterative power control scheme for use with successive interference cancellation (SIC) in the presence of cancellation errors. In [1], SIC is shown to increase the capacity of cellular CDMA systems significantly, even if the signal cancellation is imperfect due to estimation errors. However, an important complication of SIC relative to conventional CDMA recei...

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 in a low-earth orbit satellite system

Successive interference cancellation is a promising technique for increasing the capacity of uplink CDMA channels. In this paper, the technique is extended to a low-earth orbit satellite channel. Unlike terrestrial cellular channels, satellite channels typically have a limited multipath profile, but significant closed-loop power control error due to the round-trip delay incurred in communicatin...
