Abstract:
1. A method for generating multi-antenna signals for a simulation of a radio link between a transmitter and a receiver, the method comprising: allocating of channel coefficients matched to modified or selected simulation conditions, the channel coefficients describing the propagation conditions to be simulated in each case between a transmitter antenna and a receiver antenna in the simulated radio link; generating, by a transmission device, weighting factors for the weighting of signals to be transmitted in each case via a transmitter antenna conditions to be simulated; calculating, by the transmission device, an incoming reception signal affected by the propagation conditions to be simulated and the weighting of signals to be transmitted, wherein the incoming reception signal is calculated for each receiver based in part on the weighting factors and the channel coefficients; generating, by a signal generator of the transmission device, a receiver signal for each receiver antenna, which corresponds to the calculated reception signal for this receiver antenna; and transmitting, for each receiver antenna, the generated receiver signal from the transmission device to an allocated reception device via a single channel for an implementation of a communication between the transmitter and the allocated reception device via the simulated radio link.
