METHOD FOR DETERMINING AN OPTIMAL PRECODING PARAMETER AND PRECODING DEVICE OF ADJUSTABLE COMPLEXITY
Abstract:
A method (400, 500, 600) for determining a value, J opt , of a precoding parameter, J, for precoding a sequence of transmit samples, s(t), for transmission in a multi-antenna system, the method comprising: obtaining (401) values of an objective function, u(J), based on a transmission period, T T , for transmitting the precoded sequence of transmit samples, s(t), a coherence time, T C , of a channel and a precoding performance function, f(J), and characteristics of a precoding performance function, f(J), the transmission period T T depending on a training period, T TR , for channel estimation, a precoding period, T P , for precoding the sequence of transmit samples, s(t), and the coherence time, T C , of the channel; and applying (402) an optimality criterion to the values of the objective function, u(J), with respect to the precoding parameter, J, in order to obtain the value J opt .
Abstract(Chinese):
