Abstract
Transmission antenna diversity can be set up on a data transmission connection between a transmitting unit, wherein there are several transmission antenna routes, and a receiving unit. A broadcast signal is transmitted through all transmission antenna routes of the transmitting unit, with the aid of these signals a choice is made in the receiving unit of the optimum transmission antenna route and a message of the choice is transmitted to the transmitting unit, which transmits user data through the transmission antenna route connected for use. The broadcast signal of each transmission antenna route can be shaped by an individual signal shaping method which is different from the others and a transmission antenna route is connected for use based on the received antenna choice message, individually for each receiving unit.
