摘要： A method for selecting a precoding matrix to be used in a MIMO communication system (100) comprising a transmitter (105), a receiver (115) and a communication channel (110), wherein the precoding matrix is used by the transmitter to precode codewords to be transmitted to the receiver over the communication channel. At the receiver, an optimum precoding matrix within a codebook of precoding matrices is determined on the base of a metric related to the power of received signal layers. An indication is then fed back from the receiver to the transmitter useful to enable the transmitter to select the optimum precoding matrix from the codebook.

摘要： An iterative multiplier circuit (10) comprises modules (15 to 18) that subdivide the respective input signals (Z n , J n ) into a first part (msb(Z n ), msb(J n )) that is the power of 2 immediately lower or equal to the input signal and a second part (Z n -msb(Z n ), J n - msb(J n )) corresponding to the difference between the input signal and the aforesaid first part. A shift module (19) generates a respective output signal through shift operations that implement the multiplication operation for numbers that are powers of 2. The circuit operates according to a general iterative scheme in which at each step three components of the output signal (X.Y) are computed, corresponding to the product of two numbers that are powers of 2 and to two products in which at least one of the factors is a power of 2. The number of steps in the iteration scheme is controllable, thus allowing to vary the accuracy with which the output value (X.Y) is calculated.
