Abstract
A system and method of transmitting and processing pilot signals includes decorrelating a pilot tone that conveys a pilot signal, performing a channel estimation based on the decorrelated pilot tone to calculate estimated channel values and positioning the estimated channel values consistent with their order in subsequent transmission units. In one embodiment, the decorrelation comprises an interleaving operation. In another embodiment, the decorrelation occurs during a channel estimation stage. The decorrelation can be performed during a channel estimation stage by interleaving and deinterleaving pilot signals in the receiver.
