Abstract :
This paper has investigated a performance evaluation for the proposed collaborative method in uplink MU-MIMO systems. We analyze the performance of the system with transmitter joint precoder on the basis of information exchange. According to comparisons in the simulation, we can find two conclusions: firstly, the preprocessing method with the help of sharing information among transmitter users can bring attractive performance improvement; secondly, performance gains also depend on the reliability of information exchange via Wi-Fi. Therefore, inspirations from the evaluation in this paper can provide us more experience and confidence about the collaborative method for further researches.
