Multiuser Detection For Asynchronous ARGOS Signals [PDF]

open access: yes, 2010
In this paper, we investigate the application of multiuser detection techniques to a Low Polar Orbit (LPO) mobile satellite used in the ARGOS system. These techniques are used to mitigate the multiple access interference in the uplink transmission of the

Improved Detection in Successive Interference Cancellation NOMA OFDM Receiver

open access: yesIEEE Access, 2019
A successive interference cancellation receiver is one of the important blocks in non-orthogonal multiple access (NOMA) transmission. The quality of detection of the strongest user signals often decides about the quality of the whole system and minimizes

Soft Decoding Assisted Interference Cancellation in a Non-Binary LDPC Coded Fast Frequency Hopping Multiuser System Using Product Combining [PDF]

open access: yes, 2007
In this contribution, soft-input-soft-output (SISO) decoding aided successive interference cancellation (SIC) is considered in fast frequency hopping (FFH), M-ary frequency shift keying (MFSK) using product combining (PC), when operating in multiple ...

Successive Interference Cancellation Decoding With Adaptable Decision Regions for NOMA Schemes

open access: yesIEEE Access, 2022
In this work, we propose adaptable decision regions in the successive interference cancellation (SIC) decoder for the three-user uplink/downlink non-orthogonal multiple access (NOMA) scheme by exploiting the knowledge of the channel gains.

Successive Interference Cancellation for DS-CDMA Systems with Transmit Diversity

open access: yesEURASIP Journal on Wireless Communications and Networking, 2004
We introduce a new successive interference cancellation (SIC) technique for direct sequence code division multiple access (DS-CDMA) systems with transmit diversity. The transmit diversity is achieved with a space-time block code (STBC).

Throughput enhancement for multi-hop decode-and-forward protocol using interference cancellation with hardware imperfection

open access: yesAlexandria Engineering Journal, 2022
In this paper, we propose three interference cancellation based multi-hop decode-and-forward (DF) relaying protocols to enhance end-to-end system throughput under constraint of half-duplex and hardware imperfection.

Impact of Imperfect Parameter Estimation on the Performance of Multi-User ARGOS Receivers [PDF]

open access: yes, 2010
In this paper, we analyze the performance of Successive Interference Cancelation (SIC) receivers in the context of the ARGOS satellite system. Multi-user SIC receivers are studied in presence of imperfect estimates of signal parameters.

Multiuser Massive MIMO Systems With Time-Offset Pilots and Successive Interference Cancellation

open access: yesIEEE Access, 2019
This paper proposes time-offset pilots for a single-cell multiuser massive multiple-input multiple-output (MIMO) system and studies its performance under the minimum mean-squared error channel estimator and successive interference cancellation.
