A receiver (100) has improved signal weighting parameter estimation. The receiver receives a signal (101) having encoded data. A decision circuit (106) is coupled to the received encoded data to generate a first signal weighting parameter which is used to modify the received encoded data. The modified data is then decoded to output the decoded data. The decoded data output is then re-encoded using a technique similar to that used by the transmitter. The re-encoded data is then used to calculate a second signal weighting parameter which in turn, is used to, modify a stored replica of signal (101). The modified version of the stored replica is then decoded to yield a more accurate estimate of …

Why it's free to use
- Filed February 8, 1993 and granted June 30, 1998. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended February 8, 2013.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by February 8, 2015.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
