Patent ID: 8355459

Claim:
A method for transmitting a sequence of symbols through at least a channel in a wireless communication system, the sequence of symbols comprising at least first, second, third, and fourth symbols, the value of each symbol belonging to at least a signal constellation, the method comprising at least: coding by forming a coding matrix with said sequence of symbols, each component of the coding matrix being a linear combination of two symbols among the first, the second, the third, and the fourth symbols, transmitting first and second components of a first column of the coding matrix through, respectively, first and second transmit antennas, at a first time slot, transmitting first and second components of a second column of the coding matrix through, respectively, the first and the second transmit antennas, at a second time slot, wherein the coding matrix is defined as: ( as 1 + bs 3 - cs 2 * - ds 4 * as 2 + bs 4 cs 1 * + ds 3 * ) , s 1 , s 2 , s 3 , s 4 being respectively the first, the second, the third and the fourth symbols, the star designating the complex conjugate, and a, b, c, d being complex numbers of modulus 1.
