A rate adaptive transmission scheme for MIMO systems which can transmit a , variable number of data symbol streams provide transmit diversity for each , data symbol stream and fully utilize the total transmit power of the system and the full power of each antenna. In one method at least one data symbol , stream is received for transmission from a plurality of antennas. Each data symbol stream is scaled with a respective weight corresponding to the amount of transmit power allocated to that stream. The scaled data symbol stream(s) are multiplied with a transmit basis matrix to provide a plurality of transmit symbol streams for the plurality of antennas. The transmit basis matrix (e.g. a …

Why it's free to use
- Filed October 14, 2003 and granted July 15, 2014. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended October 14, 2023.

- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
