An Improved Interference Cancellation Scheme for Two- User MIMO-MAC
نویسندگان
چکیده
Multi-Input Multi-Output (MIMO) Multiple Access Channels (MAC) for two-user suffers from co-channel interference. For this problem, an interference cancellation scheme based on limited feedback is proposed. Through diagonalization processing for transmitted signals according to feedback information, the cochannel interference is eliminated. Not only the reliability is improved, but also each signal can be Maximum Likelihood (ML) decoded separately. Simulation results show that, compared to the existing interference cancellation scheme, the gain of the proposed scheme is 2dB at the Bit Error Rate (BER) of 10.

On Low-Complexity Full-diversity Detection In Multi-User MIMO Multiple-Access Channels
Multiple-input multiple-output (MIMO) techniques are becoming commonplace in recent wireless communication standards. This newly introduced dimension (i.e., space) can be efficiently used to mitigate the interference in the multi-user MIMO context. In this paper, we focus on the uplink of a MIMO multiple access channel (MAC) where perfect channel state information (CSI) is only available at the...
متن کاملSum Capacity of Degraded Gaussian Interference Networks
This paper determines the sum-capacity of degraded Gaussian K-user interference channels (IFCs). To this end, the paper first develops a family of genie-MAC (multiple access channel) outer bounds for Gaussian K-user interference channels. This family is based on existing genie-aided bounding mechanisms, but differs from current approaches in its optimization problem formulation and application....
متن کاملA New Space - time Coded Transmission Scheme for Two - user MIMO - MAC ⋆
A new space-time coded transmission scheme with limited feedback is proposed in order to eliminate interference for two-user MIMO-MAC. Each user employs rate-2 space-time block code with phase rotation, which requires a phase feedback. The multiuser interference is eliminated through simple addition of the received signal, and full diversity is realized. the signal to noise ratio is increased i...

In this paper, we propose an iterative detection and decoding (IDD) scheme for the uplink of coded multiuser multiple-input multiple-output (MU-MIMO) systems. The structure of the proposed soft-input soft-output (SISO) iterative (turbo) scheme is based on a multi-branch lattice reduction successive interference cancellation (MB-LR-SIC) strategy that computes in the first iteration a reliable ex...
متن کاملInterference alignment-and-cancellation scheme based on Alamouti code for the three-user multi-input-multi-output interference channel
An interference alignment (IA) scheme for interference channels was recently proposed to achieve the maximum degrees of freedom (DoF). Although most studies of IA focus on network throughput, that is, DoF, reliability in terms of diversity order is also an important performance measure. In this study, interference cancellation (IC) scheme based on Alamouti code in the multi-access scenario is a...
