摘要

为了对抗无线信道的频率选择性衰落，合作通信技术受到了广泛的关注。在无线通信系统中，协作协议用于提高总容量、提高信噪比和降低码元误码率。本文研究了基于粒子群优化(PSO)的功率分配算法在瑞利衰落和瑞利衰落条件下采用最大比组合(MRC)技术和多相移键控(M-PSK)调制的混合解码和前向(DF)/放大和前向(AF)中继协议中的性能。结果与现有的AF和DF中继协议进行了比较。与现有的AF和DF中继协议相比，混合DF/AF中继协议实现了更低的SER。

Symbol Error Rate Performance of Hybrid DF/AF Relaying Protocol Using Particle Swarm Optimization Based Power Allocation

Cooperative communications technique receive a lot of interest, to combat frequency selectivity fading of wireless channels. Cooperative protocols are used to increase the total capacity, Signal to Noise Ratio (SNR) and reduced the Symbol Error Rate (SER) in wireless communication systems. The performance of Particle Swarm Optimization (PSO) based Power Allocation (PA) for Proposed Hybrid Decode and Forward (DF)/Amplify and Forward (AF) Relaying Protocol using Maximal Ratio Combining (MRC) technique with Mary-Phase Shift Keying (M-PSK) Modulation over Rayleigh fading and Rician fading is presented in this paper. The results are compared with exiting AF and DF relaying protocols. Hybrid DF/AF Relaying Protocol achieves reduced SER compared to the existing AF and DF relaying protocol.
