- Abstract
- In orthogonal frequency division multiplexing
based wireless system, a pilot signal is often
employed to estimate channel state information
(CSI). However, the received pilot signal is
interfered by other cell interference in multi-cell
environments. We consider the estimation of CSI by
utilizing orthogonal preambles and channel
correlation.
