Abstract
A channel estimation method of a steel penetration system is configured to reduce computational complexity and required memory. The method includes: reconstructing, at a receiving end, a channel estimation with a compressed-sensing sparse reconstruction algorithm according to a received pilot signal to obtain estimation values of a channel state response of the steel penetration system; and equalizing a received signal of the receiving end according to the estimation values of the channel state response to obtain an equalized signal.
