An embodiment of a method for transmitting a sequence of symbols through at least a channel in a wireless communication system includes: forming a coding matrix with the sequence of symbols, each component of the coding matrix being a linear combination of two symbols among a first, a second, a third, and a fourth symbol (s1, s2, s3 , s4), transmitting a first component and a second component of a first column and of a second column of the coding matrix through a first transmit antenna and a second transmit antenna at a first and 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 * ) , a, b, c, d being complex numbers of modulus 1.
