Techniques to "successively" process received signals at a receiver unit in a MIMO system to recover transmitted data and to "adaptively" process data at a transmitter unit based on channel state information available for the MIMO channel. A successive cancellation receiver processing technique is used to process the received signals and performs a number of iterations to provide decoded data streams. For each iteration input (e.g. received) signals for , the iteration are processed to provide one or more symbol streams. One of the symbol streams is selected and processed to provide a decoded data stream. The interference due to the decoded data stream is approximately removed (i.e. …

Why it's free to use
- Filed May 7, 2002 and granted March 13, 2012. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended May 7, 2022.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by May 7, 2024.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
