A MC-CDMA channel estimation algorithm based on noise power estimation
Zhang Er-yang · Journal of Guilin University of Electronic Technology · 2006
LS channel estimation algorithm has low computation complexity and is easy to be implemented,but has low accuracy because of the influence of channel noise.An improved LS algorithm is presented in this paper,the algorithm increases the accuracy remarkably through restricting the channel response to the length of CP and ignoring channel noise and invalid channel response based on the noise power estimated with the virtual carriers in MC-CDMA.The algorithm described in this paper has low complexity and high accuracy and is validated by computer simulation.
