This paper proposes a novel design for linear precoder in underlay Device-to-Device (D2D) communication using cellular network, specifically for a use case with vehicle-to-vehicle communication and platooning. To increase the communication reliability, we develop an optimization algorithm for precoder that takes into account the outage probability when channel state information (CSI) is only partially...
Cooperative multi-cell MIMO techniques are well known for their outstanding capability to mitigate inter-cell interference by allowing user data to be jointly processed by several interfering base stations for the improvement of the system performance. This paper proposes an iterative algorithm that designs the precoding matrix for cooperative multi-cell MIMO downlink communications. As the demand...
In this paper, we propose a new and practical reliability-based hybrid automatic repeat request (RB-HARQ) scheme for irregular low-density parity-check (LDPC) codes. Irregular LDPC codes have an unequal error protection (UEP) property. Using this property, we find that the middle degree message nodes of irregular LDPC codes are important for HARQ systems. If we pick out the low reliable message nodes...
