Abstract
A frequency division multiplexing wireless transmission on two or more antennas with the set of symbols on subcarriers of a burst transmitted by one antenna transformed into another set of symbols on the subcarriers for the corresponding burst transmitted by another antenna. This helps overcome fading of the wireless channel by diversity.
Claims12
A method of transmission, comprising:
- (a) providing a set of N symbols where N is an integer greater than 1;
- (b) providing M-1 transformations of said set of N symbols where M is an integer greater than 1;
- (b) transmitting said set of N symbols on N subcarriers in a burst from a first antenna;
- and
- (c) transmitting each of said M-1 transformations of set of N symbols on N subcarriers in a burst from a corresponding one of M-1 antennas.

A method of transmission, comprising:
- (a) providing first and second sets of N symbols where N is an integer greater than 1;
- (b) providing M-1 transformations of said first set of N symbols and said second set of N symbols where M is an integer greater than 1;
- (b) transmitting said first and second sets of N symbols on N subcarriers in a first and a second burst from a first antenna;
- and
- (c) transmitting each of said M-1 transformations of set of N symbols on N subcarriers in a pair of bursts from a corresponding one of M-1 antennas.
