Research on Distributed Space-Time Coding Technology in Cooperative MIMO

Requirements 1 : can emulate the paper 1 "collaborative research MIMO, distributed space-time coding technology" on 5 Jie " simulation " in Figure 4 , Figure 5 , Figure 6 which 3 sup. (Simulation result graph and program)

 

 

1. In this paper, based on the regular LDPC join the collaborative MIMO the D-STBC in, that is, the LDPC code with the D-STBC cascade, the transmitting side by LDPC sent to the encoding cooperating nodes, the nodes then cooperate with D-STBC code form Forward to the sender. Made ML, the ZF - OSIC and , the RLS -  the MIMO -  performance of the three detection algorithms DFE BER comparison (note: sender to the relay node cooperative process, handles three cooperative relay node to the source signal protocol: forward amplification, decoding and forwarding coded cooperation, so that the three detection algorithms for these three protocols are done separately), and LDPC and D-STBC cooperative binding MIMO system with no LDPC codes collaborative MIMO the D-STBC Performance comparison of the system under the ML detection algorithm (only under the " coding collaboration protocol " ). (For simulation parameters, please refer to requirements Do it in the paper in 1 and specify the specific parameters in the program). .

1. The regular LDPC code added cooperative MIMO in D-VBLAST ( distributed vertical layered space time code) system , made ML, the ZF - OSIC and , the RLS -  MIMO -  performance of the three detection algorithms DFE error rate Comparison (note: in the process from the sender to the relay cooperative node, the relay cooperative node processes three protocols for the source signal: amplification and forwarding, decoding and forwarding, and encoding cooperation, so the three detection algorithms under these three protocols must be done separately ), and LDPC and D-VBLAST cooperative binding MIMO system with no LDPC codes cooperative MIMO of D-VBLAST system ML compare the performance of the detection algorithm. (For simulation parameters, please refer to the paper in Requirement 1 , and specify the specific parameters in the program).
