The Performance Analysis of Multi-relay Parallel Cooperative Diversity Protocol
Rong Xue · Journal of Shanghai Institute of Technology · 2008
The cooperative diversity is a form of space diversity,and the terminals share their antennas and other resources to create a virtual array through distributed transmission and signal processing in wireless networks.The cooperative diversity can increase network throughput,reduce transmitting power and suppress channel fading effects.This paper analyses the performance of multi-relay parallel scenario with AF,DF and CC,respectively.The simulation results show that with more relays,the diversity gain is higher,there are more method choices and the performance is better.
