Co-channel interference cancellation with successive cancellation in narrowband TDMA systems
2000 IEEE Wireless Communications and Networking Conference. Conference Record (Cat. No.00TH8540), 2002In this paper, successive cancellation of co-channel signals is described in the context of TDMA mobile radio systems employing coherent receivers. Both symbol aligned and misaligned co-channel signals are studied. Signal separability, which is a major problem in successive cancellation of co-channel signals, is obtained using the relative timing delay

Successive narrowband interference cancellation for OFDM systems
IEEE Communications Letters, 2007We consider the problem of mitigating narrowband interference (NBI) in conventional orthogonal frequency-division multiplexing (OFDM) systems, wherein the presence of the NBI dramatically degrades the performances of both the linear zero-forcing and minimum mean-square error equalizers. A new receiver based on successive NBI cancellation is synthesized,

Lattice Reduction-Aided Successive Interference Cancelation for MIMO Interference Channels
IEEE Transactions on Vehicular Technology, 2014In multiple-input-multiple-ouput (MIMO) interference channels (IFCs), interference alignment (IA) with zero-forcing (ZF) linear detection can be used to achieve the maximum degrees of freedom (DoFs). However, ZF linear detection usually degrades the performance due to the noise enhancement in practical systems.

Successive Interference Cancellation With Feedback for Random Access Networks
IEEE Communications Letters, 2017We consider a random access network in which $K$ nodes wish to send independent packets to an access point (AP). In this letter, a novel method of feedback construction and an adaptive retransmission protocol of collided packets are proposed, which enable efficient successive interference cancellation at the AP.

Performance analyses of successive interference cancellation in vehicular network
2016 16th International Symposium on Communications and Information Technologies (ISCIT), 2016Targeting to reduce the traffic accident and improve the traffic efficiency, vehicular network is designed to do message exchange via vehicle to vehicle (V2V) and vehicle to infrastructure (V2I) communications. For V2V communications, orthogonal resources (i.e., time slot) are usually allocated for every vehicle to avoid collisions in V2V ...

Blind successive interference cancellation for DS-CDMA systems
IEEE Transactions on Communications, 2002We propose a blind successive interference cancellation receiver for asynchronous direct-sequence code-division multiple-access (DS-CDMA) systems using a maximum mean energy (MME) optimization criterion. The covariance matrix of the received vector is used in conjunction with the MME criterion to realize a blind successive interference canceler that is

On the effect of cancellation order in successive interference cancellation for CDMA systems
2003 IEEE 58th Vehicular Technology Conference. VTC 2003-Fall (IEEE Cat. No.03CH37484), 2003We study the effect of cancellation order on bit error rate (BER) performance of a code division multiple access (CDMA) system employing a linear successive interference cancellation (SIC) receiver in both an additive white Gaussian noise (AWGN) channel and a Rayleigh fading channel. Four different ordering schemes are studied.

Successive Amplify-and-Forward Relaying With Network Interference Cancellation
IEEE Transactions on Wireless Communications, 2018Successive relaying holds the promise of recovering the multiplexing loss due to the half-duplex constraint, by allowing the source and relays to transmit messages simultaneously, but it may cause severe inter-relay interference (IRI). To overcome this, we apply an amplify-and-cancel method proposed in our previous work by Chen et al.

Interference mitigation via successive cancellation in heterogeneous networks
2011 8th International Symposium on Wireless Communication Systems, 2011In this paper, we present practical interference management schemes in heterogeneous networks (HetNets) based on interference decoding and cancellation at the receivers. The underlying idea is based on Han-Kobayashi type message splitting (MS) technique [3].
