摘要： Method for transmitting a sequence of symbols through at least a channel in a wireless communication system, comprising at least the steps of : forming a coding matrix (MC) with said sequence of symbols, each component of the coding matrix (MC) being a linear combination of two symbols among a first, a second, a third and a fourth symbols (S 1 , S 2 , S 3 , S 4 ), transmitting a first and a second components of a first column and of a second column of the coding matrix through a first and a second transmit antennas (Tx1, Tx2), at a first and a second time slot (T1, T2). The coding matrix (MC) is defined as in Formula (I) wherein a, b, c, d being complex numbers of modulus 1.

摘要： A method for decoding a spatially multiplexed signal and its corresponding receiver are provided to receive optimally a spatially multiplexed signal without abandoning optimality in the conventional technology while not performing an exhaustive search operation by optimizing the performance of a receiver without generating an error propagation phenomenon. A method for decoding a spatially multiplexed signal comprises the following several steps. A set composed of possible values of the first symbol included in a constellation is selected(01). A value of the second symbol regarding each of the first symbol selected is calculated and an estimated value of the second symbol is generated(02). An Euclidean distance between a received symbol and a noiseless signal is calculated and the noiseless is defined by using the first symbol, which has the selected value, and the second symbol, which has the calculated value(03). The shortest one is selected among Euclidean distances calculated regarding differently selected values included in the set composed of the possible values of the first symbol(04). The first and the second symbols, which are matched with the selected shortest Euclidean distance, are selected(05).
