Turbo receivers for interleave-division multiple-access systems [PDF]
, 2009 In this paper several turbo receivers for Interleave-Division Multiple-Access (IDMA) systems will be discussed. The multiple access system model is presented first. The optimal, Maximum A Posteriori (MAP) algorithm, is then presented.

Multiple Access Outerbounds and the Inseparability of Parallel Interference Channels [PDF]
IEEE GLOBECOM 2008 - 2008 IEEE Global Telecommunications Conference, 2008 It is known that the capacity of parallel (multi-carrier) Gaussian point-to-point, multiple access and broadcast channels can be achieved by separate encoding for each subchannel (carrier) subject to a power allocation across carriers. In this paper we show that such a separation does not apply to parallel Gaussian interference channels in general.

Interference mitigation for non-orthogonal multiple access in heterogeneous networks
Wireless Networks, 2023 Non-orthogonal multiple access (NOMA) technique is a promising alternative for enhancing network sum-rate while increasing the interference experienced by the users. In heterogeneous networks, the signal of a NOMA user is affected by three types of interference; intra-cell, inter-cell, and inter-tier.

Partial Interference and Its Performance Impact on Wireless Multiple Access Networks
EURASIP Journal on Wireless Communications and Networking, 2010 To determine the capacity of wireless multiple access networks, the interference among the wireless links must be accurately modeled. In this paper, we formalize the notion of the partial interference phenomenon observed in many recent wireless ...

Multiple access interference rejection code: LS code
Journal of Communications and Networks, 2003 A new code, LS code, was proposed for the IMT-2000 CDMA system. The code has special properties during a specific time interval: 1) perfect autocorrelation, and 2) perfect crosscorrelation. Perfect autocorrelation means maximum autocorrelation for zero time-offset and zero autocorrelation for all other times during a specific time interval.

EURASIP Journal on Wireless Communications and Networking, 2022 In multiple users (MU) multiple input multiple output (MIMO) systems, the non-orthogonal multiple access (NOMA) method can provide multiple access. However, a spectrum efficiency of NOMA method is restricted because of remaining an interference signal of
