In this paper, a SVD based multicell MU-MIMO uplink transmission and joint detection (JD) scheme is presented. It can decompose the MU-MIMO system into SU-MIMO channel and then the simplified JD algorithm can be performed at the cooperative eNBs. The system capacity with perfect CSI and the outage probability with imperfect CSI are analyzed. Simulation results show that this scheme is a feasible transmission...
In this paper, we have proposed link balancing scheme based on MIMO switching for the high speed wireless access system via dual-hop MIMO relays, and analyzed the capacity of different MIMO transmission mode. From these studies, we can conclude that the relayed MIMO system can support high speed group mobility and the link balancing method is able to enhance the transmission performance.
In this paper, a SVD based multicell MU-MIMO uplink transmission and joint detection (JD) scheme is presented. It can decompose the MU-MIMO system into SU-MIMO channel and then the simplified JD algorithm can be performed at the cooperative eNBs. The pairwise error probability (PEP) of each link is derived and the system capacity with perfect CSI is analyzed. Simulation results show that this scheme...
In this paper, we proposed a joint design scheme between sphere decoding and user scheduling for multiuser MIMO uplink system. This is a cross layer design scheme which adopt the channel quality information based on user scheduling to reduced the search radius of sphere detector, it leads the better bit error ratio performance and low complexity than conventional sphere detection with fixed search...
This paper addresses the problem cooperative downlink transmission in multicell multiantenna cellular networks. We have presented scheme for base station coordination and cooperation in MIMO with zero forcing beamformig system. Firstly, a projected channel matrices is given and it make the beams steer into the preferred user direction. Secondly, partial collaboration transmission and distributed scheduling...
In this paper, we proposed a computationally efficient sphere decoding method for MIMO OFDM system with the aid of HARQ. This is a cross layer design scheme which adopt the SNR updating information based on retransmission operation to reduced the search radius of sphere detector, it leads the low complexity of sphere detection. Further more, a modification of sphere decoding is proposed to handle...
