Multiple input and multiple output (MIMO) and space division multiple access (SDMA) method and apparatus for orthogonal pilot tone mapping in the system .

摘要

The method and apparatus of the orthogonal pilot tone mapping in SDMA and MIMO is disclosed. Method, and may identify symbol periods in which symbols representative of encoded data is to be transmitted in a spatial stream over a communication channel; pilot tone values ​​for the pilot tone in the symbol period to generate the pilot tone mapping to identify, when receiving at least some of the pilot tone multiple pilot tone values ​​are identified, the receiver signal that allows the receiver to reduce to characterize the communication dysfunction any There it is intended to be provided, when obtaining potentially benefits of diversity transmit spatial streams and combined symbol exceeds the dimension of at least one, two, and orthogonal least one of the pilot tone values; and a thing of sending a pilot tone and a large number of symbols through multiple spatial streams for a number of symbol periods.
