Abstract

The static or mobile radio station (BTS) has a number of complex weighted transmission signals provided via respective transmission paths with corresponding HF transmission stages (TX), connected to respective antenna elements of an antenna array. A modulation stage (MOD) and an associated control (CTR) are inserted in the transmission path for complex weighting of the transmitted signals, via respective phase shifts and/or amplitude weightings.
