ABSTRACT:
In a wireless communication system, a method for estimating a transmitted signal is disclosed. A wireless signal is received that includes a pilot channel and at least one other channel. A transmitted signal is estimated using an equalizer and the received wireless signal. The equalizer includes a filter with a plurality of taps that are adapted through use of an adaptive algorithm that uses an estimated pilot estimated from the received wireless signal. The pilot channel is transmitted in the wireless signal that included the at least one other channel. The estimated pilot is extracted and provided to the adaptive algorithm.
