In mobile communication channels information symbols
are transmitted through a communication
channel that is prone to fading and multipath
propagation. At the receiver, the effect of multipath
propagation is reduced by a process called channel
equalization. Channel equalization relies on an
accurate estimate of the channel state information
(CSI). This estimate is obtained using a channel
estimation algorithm. Mobile WiMAX is a recently
released technology that makes use of an
orthogonal frequency division multiplexing (OFDM)
based physical layer to transmit information over
a wireless...
