The present invention provides a method and an apparatus for measuring a
reception quality on a wireless communication link to a receiver by
removing a bias in a plurality of received pilot symbols and obtaining a
channel estimate for a channel, such as a wireless propagation channel,
after substantially removing the bias. For a receiver, such as a rake
receiver disposed in a base transceiver station, a bias removal module
may extract a plurality of coefficients from a wireless propagation
channel to remove a bias before a detector may receive the plurality of
pilot symbols in the data stream to determine an error rate of the
received pilot symbols where channel estimation is based on the received
pilot symbols. In this manner, a systematic flaw in a link quality
measurement based on an error rate of the received pilot symbols may be
resolved for wireless communication systems.
