Multiple Access Interference Suppression for TWSTFT Applications

IEEE Transactions on Instrumentation and Measurement, 2017
Multiple access interference (MAI) is one of the unstable sources of the two-way satellite time and frequency transfer (TWSTFT), and causes an estimation error of the signal arrival time. To suppress MAI, the successive interference cancellation (SIC) procedure is implemented on the software-defined receiver.

Performance Analysis of Multiple-Access Channel in the Presence of Multiple Interferers

2011 IEEE 73rd Vehicular Technology Conference (VTC Spring), 2011
In this paper, we consider a Rayleigh fading multiple-access interference channel where a group of users communicate with a receiver in the presence of multiple Gaussian interferers. We derive the closed-form analytical expressions for the ergodic sum-capacity in case of uncorrelated multiple-input multiple-output (MIMO) channel and spatially ...

New opportunistic interference alignment in MIMO interference multiple access channels

2016 8th International Conference on Wireless Communications & Signal Processing (WCSP), 2016
In this paper, we investigate the K-cell multiple input multiple output (MIMO) interference multiple-access channel (IMAC) where opportunistic user scheduling and interference alignment (IA) are combined. For traditional opportunistic IA (OIA) scheme, without consideration on enhancing the effectiveness of the desired signal, each user calculates its ...

On feasibility of interference alignment and cancellation for Gaussian interference multiple access channel

2012 IEEE International Conference on Communications (ICC), 2012
The feasibility condition for interference alignment (IA) with no channel extension has not been known yet. In this paper, for the first time, we explore the feasibility of interference alignment and cancellation (IAC) which has been proposed for IA with no channel extension. We investigate IAC for the Gaussian interference multiple access channel (MAC)

Tandem Spreading Multiple Access with Successive Interference Cancellation

2019 IEEE/CIC International Conference on Communications in China (ICCC), 2019
Grant-free non-orthogonal multiple access (NOMA) is adopted to serve massive machine-type devices in massive machine-type communications (mMTC). One major challenge of the grant-free NOMA for mMTC is the collision induced by nonorthogonal resource allocation.

On bounds for the cognitive multiple access Z-Interference Channel

2015 IEEE 14th Canadian Workshop on Information Theory (CWIT), 2015
The Cognitive Multiple Access Z-Interference Channel consists of a MAC channel that receives interference from an external transmitter. In a previous work we studied this model where both MAC users are cognitive and showed that an encoding scheme based on Dirty Paper coding attains the capacity region for the Gaussian case.

Resource Allocation Strategy in Multiple Access Interference Channel

2014 IEEE 80th Vehicular Technology Conference (VTC2014-Fall), 2014
Duality relations among achievable QoS parameters help us transform the problems in the broadcast channel to convex problems in multiple access channels. But a multiple access channel being considered as dual of a broadcast channel must exploit the additional freedom of power allocation traditionally considered only in a broadcast channel.

Multiple access on narrowband interference channels

IEEE GLOBECOM 1998 (Cat. NO. 98CH36250), 2002
We investigate the influence of narrowband interference on different multiple access techniques including classic frequency-division multiple access (FDMA), time-division multiple access (TDMA), code-division multiple access (CDMA), and orthogonal FDMA (OFDMA).

Multiple-Access Interference

2011
Dramatic growth rates in capacity demands in wireless and other broadband systems have resulted in a rise in the use of communication networks in which multiple users share common communication resources. A significant consequence of this trend is the increasing presence of multiple-access interference (MAI), which arises in communication systems ...

Strong interference conditions for Multiple Access-Cognitive Interference Channel

2011 12th Canadian Workshop on Information Theory, 2011
In this paper, we analyze the capacity region of a communication network where a Multiple Access Channel (MAC) and a point-to-point channel share a same medium and interfere with each other, where the transmitter of the point-to-point channel has cognitive capabilities.
