Abstract:
A method of and a precoding device and a communication device for precoding transmit data signals in a wireless Multiple-Input Multiple-Output, MIMO, channel transmission scheme for maximizing channel capacity of the MIMO system given available amounts of transmit power. The precoding is expressed in a complex precoding matrix (W), which is calculated involving individual transmit power constraints of the multiple outputs (71, . . . , 7t) of the MIMO channel. The individual transmit power constraints are comprised of predetermined individual output transmit power amplifier (PA1, . . . , PAt) limitations.
