Abstract
The present invention discloses a method for generating a signal stream in a multiple-input-multiple-output (MIMO) channel of a wireless communications system. The method comprises encoding at least one transmitting message into a first signal sequence, transforming the first signal sequence into a second and a third signal sequence by a first and a second predetermined rule, respectively, coupling the second signal sequence to a first antenna, coupling the third signal sequence to a second antenna, transmitting a signal stream comprising the first and second signal sequences to a mobile station.

A method for generating a signal stream in a multiple-input-multiple-output (MIMO) channel of a wireless communications system, the method comprising:
- encoding at least one transmitting message into a first signal sequence;
- transforming the first signal sequence into a second and a third signal sequence by a first and a second predetermined rule, respectively;
- coupling the second signal sequence to a first antenna;
- coupling the third signal sequence to a second antenna;
- transmitting a signal stream comprising the first and second signal sequences to a mobile station.
A wireless station for generating a signal stream in a multiple-input-multiple-output (MIMO) channel of a wireless communications system, the station comprising:
- a first and a second antenna;
- an encoder for generating a first signal sequence from at least one transmitting message;
- and
- a signal transformation module generating a second and a third signal sequence for being coupled to the first and second antenna, respectively,
- wherein the wireless station transmits a signal stream comprising the second and third signal sequences to a mobile station.
