Towards collisions: An enhanced successive interference cancellation with asynchronism
2012 IEEE Global Communications Conference (GLOBECOM), 2012In this paper, we consider a hidden terminal scenario where two transmitters A and B, hidden to each other, wish to communicate to a common access point, AP. When a collision occurs at AP, due to the inherent asynchrony between the colliding packets, the mutual interference between them is effectively decreased.

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,

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

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.

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

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 ...

On the capacity of a random access channel with successive interference cancellation
2015 IEEE International Conference on Communication Workshop (ICCW), 2015Successive interference cancellation (SIC), which allows one to recover additional information from otherwise lost collision signals, has been proposed in a variety of communication systems. In this paper, we introduce a random access protocol operating on channel supporting SIC that achieves a maximum stable throughput (MST) of 1.

Successive interference cancellation for two-group resource allocation
2011 IEEE 22nd International Symposium on Personal, Indoor and Mobile Radio Communications, 2011An energy allocation scheme is developed for multi-code code division multiple access (CDMA) systems to allocate the total energy to two-groups of code channels whilst considering successive interference cancellation to minimize the allocated energy. With a simplified energy calculation formulation, the required computational complexity to improve the ...
