Investigation of Fiber Length Differences in Distributed MIMO Sigma-Delta-over-Fiber Systems
Journal article, 2023
The effect of having different fiber length to each access point in distributed MIMO is experimentally investigated through testbed experiments. It is found that the delay differences can severely degrade the performance of the system. A method for compensating the delay effect is proposed.
